Copper(I) thiocyanate-amine networks: Synthesis, structure, and luminescence behavior
A series of metal-organic networks of CuSCN were prepared by direct reactions with substituted pyridine and aliphatic amine ligands, L. Thiocyanate bridging is seen in all but 1 of 11 new X-ray structures. Structures are reported for (CuSCN)L sheets (L = 3-chloro- and 3-bromopyridine, N-methylmorpholine), ladders (L = 2-ethylpyridine, N-methylpiperidine), and chains (L = 2,4,6-collidine). X-ray structures of (CuSCN)L2 are chains (L = 4-ethyl- and 4-t-butylpyridine, piperidine, and morpholine). A unique N-thiocyanato monomer structure, (CuSCN)(3-ethylpyridine)3, is also reported. In most cases, amine ligands are thermally released at temperatures 100 °C. Strong yellow-to-green luminescence at ambient temperature is observed for the substituted pyridine complexes. High solid state quantum efficiencies are seen for many of the CuSCN-L complexes. Microsecond phosphorescence lifetimes seen for CuSCN-L are in direct contrast to the nanosecond-lifetime emission of CuSCN. MLCT associated with pyridine π* orbitals is proposed as the excitation mechanism.

Measurement of Antioxidant Capacity by Electron Spin Resonance Spectroscopy Based on Copper(II) Reduction
A new method is proposed for measuring the antioxidant capacity by electron spin resonance spectroscopy based on the loss of electron spin resonance signal after Cu2+ is reduced to Cu+ with antioxidant. Cu+ was removed by precipitation in the presence of SCN-. The remaining Cu2+ was coordinated with diethyldithiocarbamate, extracted into n-butanol and determined by electron spin resonance spectrometry. Eight standards widely used in antioxidant capacity determination, including Trolox, ascorbic acid, ferulic acid, rutin, caffeic acid, quercetin, chlorogenic acid, and gallic acid were investigated. The standard curves for determining the eight standards were plotted, and results showed that the linear regression correlation coefficients were all high enough (r > 0.99). Trolox equivalent antioxidant capacity values for the antioxidant standards were calculated, and a good correlation (r > 0.94) between the values obtained by the present method and cupric reducing antioxidant capacity method was observed. The present method was applied to the analysis of real fruit samples and the evaluation of the antioxidant capacity of these fruits. (Graph Presented).

CuO/CuSCN valence state heterojunctions with visible light enhanced and ultraviolet light restrained photocatalytic activity
CuSCN is applied, for the first time, in a photocatalytic system to form CuO/CuSCN valence state heterojunctions, which exhibited enhanced visible light driven photocatalytic activity and, surprisingly, ultraviolet light restrained activity. Proper migration of photo-generated carriers is proposed to explain the photocatalytic process. This journal is the Partner Organisations 2014.

Ferro- and antiferromagnetic interactions of layer-structured basic copper compounds as studied by solid-state high-resolution deuterium NMR
Magnetic local structure of a ferromagnetic layer-structured basic copper compound Cu2(OD)1.96(C4H6 (COO)2)1.020.07D2O with dicaboxylate anion was examined by solid-state high-resolution deuterium NMR above 200 K. The magnetic interaction in a copper layer was probed by the isotropic D NMR shift of OD- ions. Only one strong signal was observed for the OD- ions of Cu2(OD)1.96(C4H6 (COO)2)1.020.07D2O, while more than two signals corresponding to different magnetic chains of Cu2+ ions in a layer were observed for most of Cu2(OD)3X where X was univalent anion. A ferromagnetic exchange interaction J = +71 K within a copper layer was estimated from the temperature dependence of the isotropic D NMR shift by assuming an one-dimensional Heisenberg model. A layer-structured compound Cu2(OH)3(SCN) with non-oxygen atom coordination for bridging copper ions was synthesized by anion exchange reaction. The magnetic susceptibility measurement indicates that a weak ferromagnetic interaction dominates in the high temperature region and a weak antiferromagnetic interaction appears in the low temperature region.

Transitionmetal complexes with pyrazole-based ligands: Part 21. Thermal decomposition of copper and cobalt halide complexes with 3,5-dimethyl-1- thiocarboxamidepyrazole
The thermal decomposition of Cu2L2Cl4, Cu2L2Cl2, Cu2L2Br 2 and Co2L2Cl4 complexes (L=3,5-dimethyl-1-thiocarboxamidepyrazole) is described. The influence of the central ion to ligand mole ratio on the course of complex formation is examined in reaction of L with copper(II) chloride. In Cu(II):L mole ratio of 1:1, in methanolic solution the reaction yields to yellow-green Cu2L 2Cl4 crystals. In the filtrate a thermodynamically more stable orange Cu2L2Cl2 copper(I) complex is forming. With a Cu(II):L mole ratio of 1:2 only the latter compound is obtained. The composition and the structure of the compounds have been determined on the basis of customary methods. On the basis of FTIR spectrum of the intermediate which is forming during the thermal decomposition of Cu2L 2Cl2 a decomposition mechanism is proposed.

Facile synthesis of a hierarchical CuS/CuSCN nanocomposite with advanced energy storage properties
We introduce CuS/CuSCN nanocomposites as active materials in pseudocapacitors, in which the redox reactions of both CuS and CuSCN simultaneously contribute to energy storage. This nanocomposite is prepared using an in situ methodology via facile, low-energy-consuming green nanochemistry. The CuS/CuSCN nanocomposites offer a high capacitance compared to their individual constituents. CuS nanorods (～15 nm) are anchored on the surface of CuSCN nanosheets (～100 nm) and they interconnect the CuSCN nanosheets, producing mesoporous nanoclusters with a large surface area, thus improving the charge transfer efficiency. The CuS/CuSCN nanocomposites exhibit high electrical conductivity and strong redox reactivity, and in particular, the pseudocapacitor with a compositional ratio of 1:1 exhibits the highest charge transfer efficiency. Consequently, the 11 CuS/CuSCN active material exhibits a high energy density (approximately 63 W h kg-1) and a high power density (1.9 kW kg-1 at 9.0 W h kg-1) as a single electrode. The highest specific capacitance is measured to be 1787.3 F g-1 in the single electrode. Furthermore, an aqueous asymmetric hybrid supercapacitor based on the CuS/CuSCN 1:1//activated carbon (AC) shows an approximately four times increase in the power density (7.9 kW kg-1), compared to the single electrode.

Synthesis, spectral studies of cobalt(II) tetrathiocyanoto dicuperate(I) complexes with some acylhydrazones and their antimicrobial activity
Cobalt(II) complexes of the type Co[Cu(NCS)2]2 ? L, where L is acetophenonebenzoylhydrazone (Abh), acetophenoneisonicotinoylhydrazone (Ainh), acetophenonesalicyloylhydrazone (Ash), acetophenoneanthraniloylhydrazone (Aah), p- hydroxyacetophenonebenzoylhydrazone (Phabh), p- hydroxyacetophenoneisonicotinoylhydrazone (Phainh), p- hydroxyacetophenonesalicyloylhydrazone (Phash), and p- hydroxyacetophenoneanthraniloylhydrazone (Phaah) were synthesized and characterized by elemental analyses, molar conductance, magnetic moments, electronic and IR spectra, and X-ray diffraction studies. The complexes are insoluble in common organic solvents and are non-electrolytes. These complexes are coordinated through the >C=O and >C=N groups of the hydrazone ligands. The magnetic moments and electronic spectra suggest a spin-free octahedral geometry around Co(II). The X-ray diffraction parameters (a, b, c) for Co[Cu(SCN)2]2 ? Ainh and Co[Cu(SCN)2] 2 ? Phabh correspond to orthorhombic and tetragonal crystal lattices, respectively. The complexes show a fair antifungal and antibacterial activity against a number of fungi and bacteria. The activity increases with increasing concentration of the compounds.

Growth mechanisms of CuSCN films electrodeposited on ITO in EDTA-chelated copper(II) and KSCN aqueous solution
Electrodeposition of β-CuSCN films was investigated on transparent conducting ITO substrates in an aqueous electrolyte containing EDTA-chelated Cu(II) and KSCN. It has been observed that the instability of CuSO4 and KSCN aqueous solution without EDTA is due to the formation of Cu(SCN) 2 precipitation, which can transform into CuSCN and (SCN)x at room temperature. Research results illuminate that the deposited film at -0.5 V versus Ag/AgClsat at 298 K is uniform and dense and composed of nanocrystals. The film is p-type with stoichiometric excess of SCN and a direct transition gap of 3.7 eV. Deposition mechanisms of CuSCN films at varied temperatures are studied based on the proposed energetic model. At or below room temperature, the electron quantum tunnel through deposition layer is predominant at the very beginning. However, the growth is limited when the thickness of CuSCN film reaches the size comparable to the diffusion length of electrons. Above room temperature, the thermal activation of surface states plays an important role in the continuous growth of large crystals through holes transport in the valence band. The calculated activation energy for crystal growth is 0.5 eV.

Fabrication of upended taper-shaped cuprous thiocyanate arrays on a copper surface at room temperature
A new strategy has been well designed to form upended taper-shaped cuprous thiocyanate (hereafter abbreviated as CuCNS) arrays on a copper substrate with use of a simple solution-phase method at room temperature. This method consists of a liquid-solid reaction between a solution of thiocyanate ammonium and the copper substrate itself in the assistance of formamide. Novel CuCNS arrays are approximately perpendicular to copper substrate surfaces. Every single crystal shows an upended taper-like morphology (i.e., the tip end points into the surface of copper substrate and the other big end of the taper exposes out, like a dart thrusting into the copper substrate). On the basis of structure and chemical bond analysis, CuCNS crystals tend to grow along the c-axis, which is essential for the formation of CuCNS arrays on a copper substrate. This approach also provides a facile strategy to produce different patterns on different copper substrates, which may be applicable to the synthesis of other inorganic materials with various potential applications.

Electrodeposition of p-type CuSCN thin films by a new aqueous electrolyte with triethanolamine chelation
A stable aqueous electrolyte solution containing Cu2+ and SCN- was prepared by adding triethanolamine (TEA, N(CH 2CH2OH)3) to chelate with Cu(II) cations. The electrolyte solutions were basic, with pH values in the range of 8.5-9, and could be used in the electrodeposition of CuSCN as a hole-conducting layer on a ZnO substrate and as an electron-conducting layer for nanocrystal photovoltaic cells because it could prevent the ZnO layer from acidic etching. CuSCN films were potentiostatically deposited on indium tin oxide glass substrates through the aqueous solutions, and the deposition potential for the sole CuSCN phase layer was determined by a linear sweep voltammetry measurement. The influence of applied potentials, electrolyte components, and deposition temperatures on the stoichiometry, phase, and particle morphology of the CuSCN films was investigated by X-ray photoelectron spectra, X-ray diffraction, and a field-emission scanning electron microscope. The results showed that the morphology of the dense CuSCN films was trigonal pyramid and the stoichiometric portions of SCN/Cu were excess of SCN. The current-voltage (I-V) characteristic of the junction between electrodeposited CuSCN and ZnO nanostructured layer displayed p-type semiconductor characteristics of CuSCN. The transmittance measurements detected high transmittance (≥87%) in the visible wavelength range, and the direct transition band gap calculated was 3.88 eV.

Synthesis, molecular structures and ESI-mass studies of copper(I) complexes with ligands incorporating N, S and P donor atoms
Equimolar reaction of copper(I) bromide with 2-thiouracil (tucH2) in acetonitrile-methanol formed a light yellow solid which on subsequent treatment with a mole of triphenyl phosphine (PPh3) in chloroform has yielded a sulfur-bridged dinuclear complex, [Cu2Br2(μ-S-tucH2)2(PPh3)2] 2CHCl3 1. A reaction of copper(I) bromide with two moles of 2,4-dithiouracil (dtucH2) in acetonitrile-methanol followed by addition of two moles of PPh3, designed to form [Cu(μ-S,S-dtuc)2(PPh3)4Cu] 2a, instead resulted in the formation of previously reported polymer, {CuBr(μ-S,S-dtucH2)(PPh3)}n 2. Reaction of copper(I) iodide with 2-thiouracil (tucH2) and PPh3 in 1:1:2 molar ratio (Cu:H2tuc:PPh3) as well as that of copper(I) thiocyanate with pyridine-2-thione (pySH) or pyrimidine-2-thione (pymSH) and PPh3 in similar ratio, yielded an iodo-bridged unsymmetrical dimer, [(PPh3)2(μ-I)2Cu(PPh3)] 3 and thiocyanate bridged symmetrical dimer, [(PPh3)2Cu(μ-N,S- SCN)2Cu(PPh3)2] 4, respectively. In both the latter reactions, thio-ligands which initially bind to Cu metal center, are de-ligated by PPh3 ligand.

On ammonium-bis(dithiocarbamato)-copper(I)-monohydrate and Mono(dithiocarbamato)-copper(I)
The title compounds NH4[Cu(S2CNH2) 2]·H2O (A) and CuS2CNH2 (B) were prepared from aqueous alcoholic solutions by reaction of ammoniumdithiocarbamate with copper sulfate in presence of excess cyanide as reductive. (A) crystallizes in the orthorhombic space group C2221 (No. 20) with a = 8.9518(6), b = 9.6414(6) and c = 10.6176(8) A, Z = 4. (B) crystallizes in the orthorhombic space group P212 121 (No. 19) with a = 5.9533(4), b = 6.6276(4) and c = 9.4834(5) A, Z = 4. In the crystal structure of (A) copper has a tetrahedral surrounding of four monodentate dithiocarbamate ligands. These structural units form 2D nets stacked along [001]. Staggered chains consisting of H2O and NH4+ penetrate the crystal structure along [001] yielding additional coherence via hydrogen bonds. The crystal structure of (B) comprises a three-dimensional tetrahedral framework of CuS 4 units exclusively linked by vertices. The arrangement is reminiscent of a filled β-cristobalite structure with the dithiocarbamate ligands extending into the hollow spaces. Thermal decomposition precedes stepwise finally giving Cu2S in each case.

Aqueous phase self-assembly of nanoscale p-n heterojunctions
Methods, adapted from photographic microcrystal growth technology, are used to assemble organized ternary organo-inorganic, nanoscale heterostructures. The resulting ensemble consists of free-standing, oriented AgBr microcrystals, upon the ???111??? surfaces of which is self-assembled a monolayer of spectrally sensitizing dye, and upon the corners of the hexagonally shaped AgBr substrates are epitaxially grown nanoscale p-type CuSCN nodules. EPR spectroscopy and photophysical measurements are employed to show that the ensembles are capable of separating photogenerated geminate pairs. One of the remarkable features of this approach is that it utilizes the ultrafast kinetics of aqueous precipitation and, thus, allows the assembly of heterostructures at rates of 1010/s?·L, or greater.

Electrochemical deposition of p-type CuSCN in porous n-type TiO2 films
We present an energy band model and a method for filling p-type CuSCN in n-type porous TiO2 film. The energy band model is based on the interface energy levels between TiO2/CuSCN heterojunction and the aqueous electrolyte. The whole deposition process is divided into three stages: the uniform nucleation on the internal surface at positive potential, the crystal growth with the cathodic potential shifting negatively and the thermal activated growth at constant potential. This was demonstrated by the electrochemical experiment combining the hydrothermal process. It was found that the obtained TiO2/CuSCN heterojunction exhibited good rectification characteristics, indicating that an intimate electrical contact was formed between the large internal surface of TiO2 film and CuSCN. This novel hydrothermal-electrochemical method may be valuable for fabricating extremely thin absorber (eta)-solar cells and other semiconductor devices.

Electrochemical deposition characteristics of p-CuSCN on n-ZnO rod arrays films
p-CuSCN/n-ZnO rod array heterojunctions were electrodeposited with a weak basic (pH ～9) aqueous electrolyte solution. I-V characteristics showed the heterostructure had clear rectification, indicating good electrical contacts between ZnO rod arrays and the embedded CuSCN. The energy band model for the electrodeposition of CuSCN on ZnO rod arrays was proposed based on linear sweep voltammetric (LSV) measurements, which indicated that the electrodeposition process was the prior growth of CuSCN on bare ZnO rods according to a conduction process, followed by compact filling in the gaps of the arrays based on the thermal activation mechanism of surface states. The diode properties of the heterojunctions revealed that although deposition was dominated by thermal activation mechanism of surface states, the electrodeposition should be performed at a lower temperature in order to reach fine filling of the gaps of ZnO rod arrays.

Phase evolution of Cu-S system in ethylene glycol solution: The effect of anion and PVP on the transformation of thiourea
The transformation mechanisms of thiourea in ethylene glycol solution was systematically investigated in this report, which shows the transformation process is influenced by the anion (NO3-, Cl-, Br -) and polyvinylpyrrolidone (PVP). Thiourea (tu) isomerizes into ammonium thiocyanate when NO3- is present, regardless of the existence of PVP. For Cl-, thiourea coordinates with copper anion to form [Cu(tu)]Cl·1/2H2O complex whether PVP is present. When it comes to Br-, thiourea hydrolyzes in the cooperation of PVP or coordinates with copper anion to form [Cu(tu)Br]·1/2H2O complex without PVP. The different transformation routes will lead to different phase evolution of the Cu-S system. This work may provide a new understanding of the transformation of thiourea in ethylene glycol solution. The optical properties of the as-prepared copper sulfides exhibit signi?cant stoichiometry-dependent features which may have potential applications in semiconductor photovoltaic devices. The effect of anions and PVP on the transition of thiourea in ethylene glycol solution was studied in detail. Copyright

Semiconductor growth and junction formation within nano-porous oxides
We have developed semiconductor growth techniques for the coating and filling of nanopores in ceramic-type substrates. The main idea behind this research is to use the large inner surface of ceramics as a template for the realization of semiconductor heterojunctions with extremely large interface area. As porous substrates we use lightly sintered nanocrystalline TiO2 of 5-10 μm thickness. The pore volume in these substrates is approx. 50% and the average pore diameter is 30-50 nm. We are able to establish nanometer thick coatings on the inner surfaces of these substrates or - in a different technique - fill the pore volume with (100 ± 3)% efficiency. The growth techniques involve chemical and electrochemical methods from liquid solutions. Binary, ternary and, most recently, quaternary compounds of the II-VI and I-III-VI material systems were prepared.

The [C9H7NC3H 5]+ cations are located between the corrugated layers of the {Cu2(SCN)3-}∞ anions in compound II. As in the case of the previously studied copper(I) halide complexes, the C=C bond of the allyl group in the N-allylquinolinium cation of complexes I, II does not interact with Cu(I).

Monodisperse CuS nanodisks: Lowerature solvothermal synthesis and enhanced photocatalytic activity
Controllable synthesis of uniformly disk-shaped CuS nanostructures with a narrow size distribution was realized by a lowerature (150 °C) solvothermal process using polyvinyl pyrrolidone (PVP) as the surfactant. Monodispersed nanodisks of pure CuS phase with an average diameter of ca. 500 nm could be obtained at a specific S/Cu molar ratio (xS/Cu) of raw materials, which was revealed to affect the phase structure and morphology of the product but the influence of PVP content (xPVP) is limited. The CuS nanodisks have a broad absorption in the visible region and superior photocatalytic performances for the degradation of RhB whose decomposition rate reaches 93% in 2 h, indicating a potential application in the field of wastewater treatment.

Synthesis and crystal structure of Me3NHCu2(SCN)3, Me2C=NMe2Cu2(SCN)3, and Me2C=NMe2Ag2(SCN)3. Three-dimensional networks of thiocyanatometallates(I)
Attempts to build up polyanionic networks on the basis of thiocyanatometallates of Cu1 and Ag1 led to the synthesis of three new tris(thiocyanato)dimetallates(I) A[M2(SCN)3] with M = Cu, Ag and A = Me3NH and A = [Me2CNMe2]. The crystal structures show distorted tetrahedral [M(SCN)3(NCS)] and [M(SCN)2(NCS)2] building groups interlinked by SCN bridges. The resulting 3-dimensional frame works accommodate the counter cations in spacious voids. Me3NHCu2(SCN)3 (1) was synthesized by reaction of CuSCN with (CH3)3NHCl in the presence of an excess of KSCN in acetone. 1 crystallizes in the monoclinic space group P21/c with a = 578.4(1), b = 3025.1(5), c = 754.7(3) pm; β = 112.53°; Z = 4. The reaction of CuSCN or AgSCN with (CH3)2NH2Cl and KSCN in acetone resulted in the formation of [Me2CNMe2]Cu2(SCN)3 (2) and [Me2CN-Me2]Ag2(SCN)3 (3). Compound 2 crystallizes in the orthorhombic space group P212121 with a = 720.6(1), b= 1161.5(1), c = 1655.0(2) pm; Z = 4. The isotypical structure of 3 exhibits somewhat larger unit cell dimensions; a = 743.4(1), b = 1222.5(1), c = 1683.9(2) pm.

Full title: Synthesis and structural and magnetic properties of mononuclear, dinuclear, and tetranuclear copper(II) complexes of a 17-membered macrocyclic ligand (HM3), capable of forming endogenous phenoxide and pyridazino bridges. X-ray crystal structures of [Cu2(M3)(μ2-OMe)(NO3)2], [Cu4(M3)2(μ3-OMe)2(μ 2-Cl)2Cl2], [Cu4(M3)2(μ3-OEt)2(μ 2-N3)2(N3)2](MeOH), [Cu4(M3)2(μ3-OMe)2(NCS) 4](DMF), and [Cu(M3)(NCS)2]. A series of copper(II) complexes, involving dinuclear, tetranuclear, and mononuclear derivatives, [Cu2(M3)(μ2-OMe)X2] (X = NO3 (I), CF3SO3 (II)), [Cu4(M3)2(μ3-OMe)2(μ 2-Cl)2Cl2] (III), [Cu4(M3)2(μ3-OEt)2(μ 2-N3)2-(N3)2](MeOH) (IV), [Cu4(M3)2(μ3-OMe)2(NCS) 4](DMF) (V), [Cu4(M3)2(μ3-OMe)2(μ 2-Br)2Br2]·H2O (VI), and [Cu(M3)(NCS)2] (VII), have been synthesized by template condensation of 2,6-diformyl-4-methylphenol with 3,6-bis(2-aminoethyl)thio)pyridazine (1:1), in the presence of copper(II) salts, followed, in some cases, by addition of potentially coordinating anions. The tetranuclear complexes III-VI involve an effective dimerization of two dinuclear halves, with an unusual combination of μ3-alkoxy and μ2-anion bridges in III, IV, and VI and just μ3-alkoxy bridges in V. Single-crystal X-ray structures for I, III-V, and VII have been determined. I crystallized in the monoclinic system, space group P21/n, with a = 8.6930(8) A?, b = 15.02(1) A?, c = 18.308(2) A?, β = 90.890(7)°, and Z = 4. Refinement by full-matrix least-squares procedures gave final residuals of R = 0.057 and Rw = 0.049. III crystallized in the monoclinic system, space group P21/n, with a = 11.045(2) A?, c = 16.054(6) A?, c = 12.309(2) A?, β = 90.68(2)°, and Z = 4. Refinement by full-matrix least-squares procedures gave final residuals of R = 0.032 and Rw = 0.032. IV crystallized in the monoclinic system, space group P21/n, with a = 11.077(3) A?, b = 15.153(4) A?, c = 16.492(2) A?, β = 99.45(2)°, and Z = 4. Refinement by full-matrix least-squares procedures gave final residuals of R = 0.059 and Rw = 0.049. V crystallized in the monoclinic system, space group C2/c, with a = 27.316(5) A?, b = 22.170(4) A?, c = 11.036(4) A?, β = 111.81(2)°, and Z = 8. Refinement by full-matrix least-squares procedures gave final residuals of R = 0.056 and Rw = 0.061. VII crystallized in the monoclinic system, space group P2/n, with a = 21.283(6) A?, b = 11.367(6) A?, c = 21.679(4) A?, β = 116.73(1)°, and Z = 8. Refinement by full-matrix least-squares procedures gave final residuals of R = 0.042 and Rw = 0.035. Low magnetic moments are observed for all the polynuclear complexes, signifying the presence of intradimer antiferromagnetic coupling. This has been confirmed by variable-temperature magnetic studies, and strong exchange is observed within each dinuclear fragment (I-VI), with -2J > 445 cm-1 in all cases. Weak interdinuclear ferromagnetic exchange is apparent in two cases, but for complex IV, in which bridging azides link the dinuclear halves, much stronger antiferromagnetic interdimer coupling appears to exist.
