“…The peaks of binding energy at 161.9 eV and 163.2 eV are assigned to Cu-S and In-S bond structure in CIS, which are not symmetric peaks owing to the responses of Cu-S and In-S, consistent with that of CuInS 2 . 38 The Bi 4f peaks of the sample are located at 158.5 eV (Bi 4f 7/2 ) and 163.8 eV (Bi 4f 5/2 ), which are in agreement with that of Bi 2 S 3 in literature. 39 Combined with the XRD analysis, it can be corroborated that the CIS and BS nanoparticles are successfully deposited on the surface of TiO 2 nanorods, and there are no obvious impurities existing in the asobtained TiO 2 /CIS/BS CSS nanorods.…”

“…The transformation can be carried out in the presence of either OA or DDT as capping agents. Most impressively, in the presence of OA, the zinc blende phase results, while with added DDT the kinetically 559 and recently, the PL behavior of primarily CuInS 2 QDs prepared by this method but using [In(S 2 CN i Pr 2 ) 3 ] as the indium source was detailed.

Nanodimensional metal sulfides are a developing class of low-cost materials with potential applications in areas as wide-ranging as energy storage, electrocatalysis, and imaging. An attractive synthetic strategy, which allows careful control over stoichiometry, is the single source precursor (SSP) approach in which well-defined molecular species containing preformed metal–sulfur bonds are heated to decomposition, either in the vapor or solution phase, resulting in facile loss of organics and formation of nanodimensional metal sulfides. By careful control of the precursor, the decomposition environment and addition of surfactants, this approach affords a range of nanocrystalline materials from a library of precursors. Dithiocarbamates (DTCs) are monoanionic chelating ligands that have been known for over a century and find applications in agriculture, medicine, and materials science. They are easily prepared from nontoxic secondary and primary amines and form stable complexes with all elements. Since pioneering work in the late 1980s, the use of DTC complexes as SSPs to a wide range of binary, ternary, and multinary sulfides has been extensively documented. This review maps these developments, from the formation of thin films, often comprised of embedded nanocrystals, to quantum dots coated with organic ligands or shelled by other metal sulfides that show high photoluminescence quantum yields, and a range of other nanomaterials in which both the phase and morphology of the nanocrystals can be engineered, allowing fine-tuning of technologically important physical properties, thus opening up a myriad of potential applications.

“…Other copper dithiocarbamates can also be used as SSPs. For example, wurtzite CuInS 2 nanocrystals have been prepared in OLA at 200 • C using [Cu(S 2 CNBu 2 ) 2 ] [196], while the indium source can also be varied to afford mixtures of wurtzite and chalcopyrite phases, which show dual emission in the visible (600-700 nm) and near-IR (700-800 nm) [197]. The decomposition of mixtures of [Cu{S 2 CMe(CH 2 CH 2 OH)} 2 ] and [In{S 2 CMe(CH 2 CH 2 OH)} 3 ] affords ternary nanoparticles (CuInS 2 ) of the wurtzite phase.…”

Copper dithiocarbamate complexes have been known for ca. 120 years and find relevance in biology and medicine, especially as anticancer agents and applications in materials science as a single-source precursor (SSPs) to nanoscale copper sulfides. Dithiocarbamates support Cu(I), Cu(II) and Cu(III) and show a rich and diverse coordination chemistry. Homoleptic [Cu(S2CNR2)2] are most common, being known for hundreds of substituents. All contain a Cu(II) centre, being either monomeric (distorted square planar) or dimeric (distorted trigonal bipyramidal) in the solid state, the latter being held together by intermolecular C···S interactions. Their d9 electronic configuration renders them paramagnetic and thus readily detected by electron paramagnetic resonance (EPR) spectroscopy. Reaction with a range of oxidants affords d8 Cu(III) complexes, [Cu(S2CNR2)2][X], in which copper remains in a square-planar geometry, but Cu–S bonds shorten by ca. 0.1 Å. These show a wide range of different structural motifs in the solid-state, varying with changes in anion and dithiocarbamate substituents. Cu(I) complexes, [Cu(S2CNR2)2]−, are (briefly) accessible in an electrochemical cell, and the only stable example is recently reported [Cu(S2CNH2)2][NH4]·H2O. Others readily lose a dithiocarbamate and the d10 centres can either be trapped with other coordinating ligands, especially phosphines, or form clusters with tetrahedral [Cu(μ3-S2CNR2)]4 being most common. Over the past decade, a wide range of Cu(I) dithiocarbamate clusters have been prepared and structurally characterised with nuclearities of 3–28, especially exciting being those with interstitial hydride and/or acetylide co-ligands. A range of mixed-valence Cu(I)–Cu(II) and Cu(II)–Cu(III) complexes are known, many of which show novel physical properties, and one Cu(I)–Cu(II)–Cu(III) species has been reported. Copper dithiocarbamates have been widely used as SSPs to nanoscale copper sulfides, allowing control over the phase, particle size and morphology of nanomaterials, and thus giving access to materials with tuneable physical properties. The identification of copper in a range of neurological diseases and the use of disulfiram as a drug for over 50 years makes understanding of the biological formation and action of [Cu(S2CNEt2)2] especially important. Furthermore, the finding that it and related Cu(II) dithiocarbamates are active anticancer agents has pushed them to the fore in studies of metal-based biomedicines.
