Ultrafast Size Expansion and Turn-On Luminescence of Atomically Precise Silver Clusters by Hydrogen Sulfide

The formation of high-nuclearity silver(I) clusters remains elusive and their potential applications are still underdeveloped. Herein, we firstly prepared a chain-like thiolated AgI complex {[Ag18(StBu)10(NO3)8(CH3CN)2(H2O)2] ? [Ag18(StBu)10(NO3)8(CH3CN)6]}n (abbreviated as Ag18) in which two similar Ag18 clusters are assembled by NO3? anions. The solution containing Ag18 reacted with hydrogen sulfide with controlled concentration, promptly producing another identifiable and bright red-emitting high-nuclearity silver(I) cluster, Ag62(S)13(StBu)32(NO3)4 (abbreviated as Ag62). We tracked the transformation using time-dependent electrospray ionization mass spectrometry (ESI-MS), UV/Vis absorption and photoluminescence spectra. Based on this cluster transformation, we further developed an ultra-sensitive turn-on sensor detecting H2S gas with an ultrafast response time (30 s) at a low detection limit (0.13 ppm). This work opens a new way of understanding the growth of metal clusters and developing their luminescent sensing applications.

Acid-Base-Triggered Structural Transformation of a Polyoxometalate Core Inside a Dodecahedrane-like Silver Thiolate Shell

Self-assembly of metavanadate and organosilver(I) salts leads to a novel dodecahedrane-like [Ag30(tBuS)20]10+ silver(I) thiolate nanocage that tightly wraps an unusual C2h polyoxovanadate anion. The polyoxovanadate core undergoes transformation to a D3d configuration upon acidification, and reverts back to its original C2h structure upon addition of base. Chromism was observed for the silver(I) thiolate cluster during the configurational change of the central polyoxovanadate core; the color of the solution changes reversibly from green to dark yellow. This work represents the first reported example of chromic polyoxometalatelated silver(I) thiolate shells that respond to external acid-base stimuli. It also represents an important advance in providing crystallographic proof that structural transformations occur in a nanoscale core-shell cluster.

Syntheses, structures and characterization of heterobimetallic compounds [Et4N]2[(MS4)Ag8(SBu t)8](M = W, Mo) and {[Et4N][WOS 3Ag2(S2COEt)]}n

Three new M/Ag/S heterobimetallic compounds [Et4N] 2[(MS4)Ag8(SBut)8] (1a, M = W; 1b, M = Mo) and {[Et4N][WOS3Ag2(S 2COEt)]}n (2) have been prepared from the reactions of [MOnS4-n]2- (M = W, Mo; n = 0-1) with AgSBut or AgS2COEt. Single crystal structural studies show that the compound 1a contains a [WS4]2- dianion encapsulated in a neutral octanuclear (AgSBut)8 cage via weak Ag?S(WS4) interactions. In compound 2, butterfly WOS 3Ag2 fragments are connected via bidentate bridging [S2COEt]- ligands to give a chain polymeric anion. These compounds are fully characterized by IR, UV-vis and microanalyses. Compound 2 is the first W/Ag/S polymer with bidentate thiolato linkages.

Tandem Silver Cluster Isomerism and Mixed Linkers to Modulate the Photoluminescence of Cluster-Assembled Materials

Silver chalcogenolate cluster assembled materials (SCAMs) are a category of promising light-emitting materials the luminescence of which can be modulated by variation of their building blocks (cluster nodes and organic linkers). The transformation of a singly emissive [Ag12(SBut)8(CF3COO)4(bpy)4]n (Ag12bpy, bpy=4,4′-bipyridine) into a dual-emissive [(Ag12(SBut)6(CF3COO)6(bpy)3)]n (Ag12bpy-2) via cluster-node isomerization, the critical importance of which was highlighted in dictating the photoluminescence properties of SCAMs. Moreover, the newly obtained Ag12bpy-2 served to construct visual thermochromic Ag12bpy-2/NH2 by a mixed-linker synthesis, together with dichromatic core–shell Ag12bpy-2@Ag12bpy-NH2-2 via solvent-assisted linker exchange. This work provides insight into the significance of metal arrangement on physical properties of nanoclusters.

A {Ag17S8} cluster-based coordination polymer linked by bridging CO32? ligands

Cluster-based coordination frameworks superior to single metal-ion based coordination frameworks possess highly connected nets, large porous channels and enhanced stability. The carbonate anion (CO32?), an excellent anion template, can also serve as a rigid ligand with planar triangular geometry. It is an effective means of utilizing renewable carbon resources by the fixation of atmospheric carbon dioxide. Therefore, pursuing complex functional cluster-based coordination framework materials bridging by CO32? ligand is a sensible idea. Herein, compound {[Ag34(SBut)16(CF3COO)10(CO3)5(H2O)4][Et3N+]2}n (1) (Ag17S8 dimer) consists of a [Ag17(SBut)8(CF3COO)6(CO3)]+ cationic secondary building unit (SBU), a [Ag17(SBut)8(CF3COO)4(CO3)3(H2O)4]? anionic SBU and a bridging CO32? ligand in an asymmetric unit, which is extended into a 2D honeycomb network parallel to the bc plane with a simple topology symbol of {63}. Compound 1 has been well defined and the luminescence properties of 1 have been investigated.

Assembly of Atomically Precise Silver Nanoclusters into Nanocluster-Based Frameworks

Here, we demonstrate an approach to synthesizing and structurally characterizing three atomically precise anion-templated silver thiolate nanoclusters, two of which form one- and two-dimensional structural frameworks composed of bipyridine-linked nanocluster nodes (referred to as nanocluster-based frameworks, NCFs). We describe the critical role of the chloride (Cl-) template in controlling the nanocluster's nuclearity with atomic precision and the effect of a single Ag atom difference in the nanocluster's size in controlling the NCF dimensionality, modulating the optical properties, and improving the thermal stability. With atomically precise assembly and size control, nanoclusters could be widely adopted as building blocks for the construction of tunable cluster-based framework materials.

Self-assembly patterns of non-metalloid silver thiolates: Structural, HR-ESI-MS and stability studies

Screening of AgNO3/AgStBu solutions in DMF, DMSO and NMP resulted in the isolation of three novel nanosized silver/thiolate complexes with a torus-like {Ag20(StBu)10} core. The structures of [NO3@Ag20(StBu)10(NO3)9(DMF)6] (1) and [NO3@Ag20(tBuS)10(NO3)8(NMP)8][NO3@Ag19(tBuS)10(NO3)8(NMP)6]2(NO3) (2) were studied by single crystal X-ray diffraction (SCXRD). The self-assembly process leading to 1 can be switched to a different outcome using Br-, resulting in [Br@Ag16(StBu)8(NO3)5(DMF)3](NO3)2 (3), which is the one of the few genuine host-guest complexes in the silver/thiolate systems. Solutions of the individual complexes in CH3CN were studied by HR-ESI-MS techniques, which revealed a dynamic behavior for each complex, driven by a redistribution of the {AgNO3} units. This dynamics results in the appearance of both cationic and anionic species, based on unchanged silver-thiolate cores. Daylight causes degradation of 3 with the formation of a composite material based on defective orthorhombic Ag2S with a porous morphology, as observed using the SEM technique. The electrocatalytic HER activity of such a material was studied. This journal is

A comparative study of third-order nonlinear optical properties of silver phenylacetylide and related compounds via ultrafast optical kerr effect measurements

A comparative study of the third-order nonlinear optical properties, via the newly developed heterodyned optical Kerr effect (OHD-OKE) measurements, of silver phenylacetylide and related compounds is reported. [AgC≡CC6H5]n (1) was found to exhibit efficient third-order nonlinear optical susceptibility X(3) of 2.4 × 10-14 esu, and second hyperpolarizability γ of 9.07 × 10-32 esu. These results are compared with those of two related silver phenylacetylide compounds, namely, a double salt, (silver phenylacetylide)·(silver tert-butylthiolate) [AgC≡CC6H5·AgS (t-C4H9)]n complex (2), and a cluster, triphenylphosphine silver phenylacetylide tetramer, [(C6H5)3PAgC≡ CC6H5]4 (3), as well as that of the related organic polymer polyphenylacetylene (4). These four compounds represent different types of phenylacetylide derivatives: 1 is an organometallic polymer, 2 a polymeric double salt, 3 a discrete metal cluster, and 4 an organic polymer. It was found that the third-order optical nonlinear response was enhanced by the incorporation of silver d electrons into the delocalized conjugated organic π system, and its magnitude is highly dependent upon the extent of the π delocalization. Specifically, the relative magnitudes of X(3) and γ follow the order silver phenylacetylide polymer (1) > (silver phenylacetylide)·(silver tert-butylthiolate) double salt (2) > polyphenylacetylene polymer (4) > tetrameric (triphenylphosphine silver phenylacetylide)4 cluster (3). The observed trend may be attributed to the decreasing length of π conjugation. It is interesting to note that the incorporation of Ag(I) into the polymeric framework of polyphenylacetylene enhances the X(3) by 25-fold for the same degree of polymerization (n = 7). The signs of X(3) and γ, which are related to the response mechanisms, were found to be solvent dependent.
