Improved selectivity for Pb(II) by sulfur, selenium and tellurium analogues of 1,8-anthraquinone-18-crown-5: Synthesis, spectroscopy, X-ray crystallography and computational studies

We report here a series of heteroatom-substituted macrocycles containing an anthraquinone moiety as a fluorescent signaling unit and a cyclic polyheteroether chain as the receptor. Sulfur, selenium, and tellurium derivatives of 1,8-anthraquinone-18-crown-5 (1) were synthesized by reacting sodium sulfide (Na2S), sodium selenide (Na2Se) and sodium telluride (Na2Te) with 1,8-bis(2-bromoethylethyleneoxy)anthracene-9,10-dione in a 1:1 ratio. The optical properties of the new compounds are examined and the sulfur and selenium analogues produce an intense green emission enhancement upon association with Pb(ii) in acetonitrile. Selectivity for Pb(ii) is markedly improved as compared to the oxygen analogue 1 which was also competitive for Ca(ii) ion. UV-Visible and luminescence titrations reveal that 2 and 3 form 1:1 complexes with Pb(ii), confirmed by single-crystal X-ray studies where Pb(ii) is complexed within the macrocycle through coordinate covalent bonds to neighboring carbonyl, ether and heteroether donor atoms. Cyclic voltammetry of 2-8 showed classical, irreversible oxidation potentials for sulfur, selenium and tellurium heteroethers in addition to two one-electron reductions for the anthraquinone carbonyl groups. DFT calculations were also conducted on 1, 2, 3, 6, 6 + Pb(ii) and 6 + Mg(ii) to determine the trend in energies of the HOMO and the LUMO levels along the series.

Synthesis and Thorough Investigation of Discrete Organotin Telluride Clusters

Systematic experimental and theoretical investigations of reactions of R1SnCl3 (R1=CMe2CH2C(Me)O) with (Me3Si)2Te allowed for the stepwise formation and single-crystalline isolation of the first tin sesquitelluride clusters with functional organic ligands. Subsequent derivatization of the latter took place under reorganization of the inorganic core, affording clusters with complex hybrid architectures.

Coordination responsive tellurium-containing multilayer film for controlled delivery

A coordination-responsive tellurium containing film was fabricated for controlled release. The coordination chemistry between telluride molecules and cisplatin was utilized for the loading of cisplatin, while competitive ligands were used for triggered release. This work could enrich the coordination responsive system and further tune the release kinetics of cisplatin. This journal is

Highly reversible Na-ion reaction in nanostructured Sb2Te3-C composites as Na-ion battery anodes

Sb2Te3 and its amorphous carbon-modified nanocomposite (Sb2Te3-C) are synthesized by simple solid-state synthetic methods, and their potential as anode materials for rechargeable Na-ion batteries (NIBs) is evaluated. Ex situ X-ray diffraction and high-resolution transmission electron microscopy clearly demonstrate the sodiation/desodiation reaction mechanism of the Sb2Te3 and Sb2Te3-C nanocomposite electrodes. In both electrodes, Sb2Te3 is converted into Na3Sb and Na2Te during Na insertion. However, Na3Sb and Na2Te in only the Sb2Te3-C nanocomposite electrode recombine into the original Sb2Te3 phase after full Na extraction. As a consequence of its interesting conversion/recombination reaction during sodiation/desodiation reaction, the Sb2Te3-C nanocomposite electrode exhibits a long cycle life with highly reversible gravimetric and volumetric capacity (373 mAh g-1 and 765 mAh cm-3 over 50 cycles) and fast rate capability (1 C: 391 mAh g-1 and 802 mAh cm-3; 2 C: 377 mAh g-1 and 773 mAh cm-3).

Synthesis of Diphenylchalcogenophene Diboronic Acid Bis(pinacol) Esters and Halogen Photoelimination from Tellurium by Triplet–Triplet Annihilation

The synthesis of diphenylthiophene-, diphenylselenophene-, and diphenyltellurophene-based diboronic bis(pinacol) esters and their optoelectronic properties is reported. The addition of bromine to the borylated diaryltellurophene and subsequent photoelimination are investigated. The photochemical quantum yield of bromine photoelimination is (9.7±0.2) % at a 4.4 m trap (2,3-dimethyl-1,3-butadiene) concentration. It is found that the bromine photoelimination reaction can also be driven by the incorporation of a triplet sensitizer through a triplet–triplet annihilation process.

New Forms of CdSe: Molecular Wires, Gels, and Ordered Mesoporous Assemblies

This work investigates the structure and properties of soluble chalcogenidocadmates, a molecular form of cadmium chalcogenides with unprecedented one-dimensional bonding motifs. The single crystal X-ray structure reveals that sodium selenocadmate consists of infinite one-dimensional wires of (Cd2Se3)n2n- charge balanced by Na+ and stabilized by coordinating solvent molecules. Exchanging the sodium cation with tetraethylammonium or didodecyldimethylammonium expands the versatility of selenocadmate by improving its solubility in a variety of polar and nonpolar solvents without changing the anion structure and properties. The introduction of a micelle-forming cationic surfactant allows for the templating of selenocadmate, or the analogous telluride species, to create ordered organic-inorganic hybrid CdSe or CdTe mesostructures. Finally, the interaction of selenocadmate “wires” with Cd2+ ions creates an unprecedented gel-like form of stoichiometric CdSe. We also demonstrate that these low-dimensional CdSe species show characteristic semiconductor behavior, and can be used in photodetectors and field-effect transistors.

125Te NMR SPECTRA OF TELLURIUM HETEROCYCLES

The 125Te chemical shifts and 125Te-1H coupling constants for the heterocycle 1,3-dihydrobenzotellurophene and its dihalo oxidation products have been measured and shown to correlate with the oxidation state of the tellurium and the electronegativity of the halo substituent.Halogen exchange in mixed dihalides has also been monitored by 125Te NMR.Examination of typical Te-compounds in the oxidation states -II, +II and +IV reveals a chemical shift range of 3,500 ppm.

The electronic structures of these compounds were determined by density functional calculations and their reactivity towards Pd(0) centres was evaluated.

Sodium Substitution in Lead Telluride

Sodium is widely used as a substituting element in p-type PbTe-based thermoelectric materials. In this work, two series of polycrystalline samples Pb1-yNayTe1-y/2 (total charge balance) and Pb1-xNaxTe (total charge nonbalance) were examined. Na has limited solubility for both of the series. The MAS 23Na NMR analysis of Pb1-xNaxTe series (for Pb0.98Na0.02Te sample after spark-plasma sintering, SPS) reveals only one Na signal, corresponding to Na atoms coordinated by six Te atoms, indicating substitution of Pb by Na without defects in the Te sublattice. In the Pb1-yNayTe1-y/2 series, clustering of Na atoms with reduced coordination by Te was observed. Additional heat treatment of these samples leads to the reorganization of the Na clusters in PbTe and their equilibration with the homogenized distribution of Na in the whole volume. The maximum ZT values of 1.4-1.6 at 760 K are established for both Pb1-xNaxTe and Pb1-yNayTe1-y/2 series. Upon long-time annealing at 873 K, reorganization and redistribution of Na atoms lead to the change in carrier concentration and, consequently, the thermoelectric properties for both series.
