Copper sulphide materials have received great attention due to their low bandgap semiconducting properties. As compared to other chalcogenides, few synthetic examples have been reported, and a simple and scalable synthetic method for preparing size- and shape-controlled copper sulphide nanoparticles is required for potential wide application of these materials. Herein, a facile one pot scalable synthetic route has been developed for preparing highly monodisperse djurleite Cu1.94S hexagonal nanoplates. The thermal decomposition of a single precursor CuSCN was found suitable for preparing a large quantity of highly monodisperse Cu1.94S hexagonal nanoplates; a multi-gram scale product could be obtained in a single step. Under the synthetic scheme developed, the width of Cu1.94S nanoplates with a thickness of ~ 10 nm could be easily tuned from 70 nm to 130 nm. Their optical properties were investigated and their photothermal effect was also studied by photothermal optical coherence reflectometry (PT OCR). Cu1.94S hexagonal nanoplates showed a considerable photothermal effect, which was found to depend on the nanoparticle concentration.

The ligand bis(diphenylphosphino)aniline (dppan) has been shown to be a versatile ligand sporting different coordination modes and geometries as dictated by copper(I) and the counter ion. The molecular structures of its Cu(I) complexes were characterized by X-ray crystallography. The ligand was found in a chelating mode and monomeric complexes were formed when the ligand to copper ratio was 2:1 and the anion was non-coordinating. However, with thiocyanate as the counter anion, the ligand was found to adopt two different modes, with one ligand chelating and the other acting as a monodentate ligand. With CuX (X = Cl, Br), dppan formed a tetrameric complex when the ligand and metal were reacted in the ratio of 1:1. But reactions containing ligand and metal in the ratios of 1:2 or 2:1, resulted in the formation of a mixture of species in solution. Crystallization however, led to the isolation of the tetrameric complex. Variable temperature 31P{1H} NMR spectra of the isolated tetramers did not show the presence of chelated structures in solution. Tetra-alkylammonium salts were added to solutions of various complexes of dppan and studied by 31P{1H} NMR to probe the effect of anions on the stability of complexes in solution. The Cu-dppan complexes were robust and did not interconvert with other structures in solution unlike the bis(diphenylphosphino)isopropylamine complexes.

Application In Synthesis of Bis(acetylacetone)copperIn an article, once mentioned the new application about 13395-16-9.

The rate and activation parameters of tetraphenyltetrabenzoporphine (H 2TPTBP) complexation with 3d-metal acetates and acetylacetonates are shown to be determined by the solvent nature. With an increase in the electron-donor properties of a solvent, the reaction rate increases due to protonation of N-H bonds and decreases as MAm(Solv)n – m salt solvates become more stable. As the result, the rate of a reaction with ZnAc2 increases in the series: DMF < DMSO < Py < PrOH-1 < CH3CN < C6H6. In inert and weakly coordinating solvents, the transition state of a reaction is supposed to be formed according to the mechanism of contraction of the salt coordination sphere. The rate of H2TPTBP reaction with metal acetates in pyridine changes in the series: Cu(II) > Cd(II) > Zn(II) > Co(II), while the stability of the obtained complexes decreases in the series Cu(II) > Co(II) > Zn(II) > Cd(II). It is shown that the spectral criterion of the complex stability can be used in the series of metal complexes with one ligand, but it is violated if the ligand structure is changed.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about 13395-16-9 is helpful to your research.

Reaction of copper(II) thiocyanate with pyrimidine leads to the formation of the new ligand-rich 1:2 (1:2 = ratio metal salt to ligand) copper(II) compound [Cu(NCS)2(pyrimidine)2]n (1). Its crystal structure was determined by X-ray single crystal investigations. It consists of linear polymeric chains, in which the Cu2+ cations are mu-1,3 bridged by the thiocyanato anions. The pyrimidine ligands are terminal N-bonded to the Cu2+ cations, which are overall octahedrally coordinated by two pyrimidine ligands and two N-bonded as well as two S-bonded thiocyanato anions. Magnetic measurements were preformed yielding weak net ferromagnetic interactions between adjacent Cu2+ centers mediated by the long Cu-S distances and/or interchain effects. On heating compound 1 to approx. 160 C, two thirds of the ligands are discharged, leading to a new intermediate compound, which was identified as the ligand-deficient 2:1 copper(I) compound [(CuNCS)2(pyrimidine)]n by X-ray powder diffraction. Consequently, copper(II) was reduced in situ to copper(I) on heating, forming polythiocyanogen as byproduct. Elemental analysis and infrared spectroscopic investigations confirm this reaction pathway. Further investigations on other ligand-rich copper(II) thiocyanato compounds clearly show that this in situ thermal solid state reduction works in general. The Royal Society of Chemistry 2009.

Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Application In Synthesis of Cuprous thiocyanate. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.

Under different situations, solvothermal reactions of 3,5-diethyl-4-(4- pyridyl)-pyrazole (HL) with CuX or CuX2 (X = Cl, Br, I, and SCN) afforded five copper(I) coordination polymers, {CuX[CuL]3· solvent}n (X = Cl, 1; Br, 2; I, 3; X = SCN and solvent = MeCN, 4) and {Cu2I2[CuL]3}n (5). X-ray diffraction analyses show that all the complexes have trinuclear [CuL] 3 (referred as Cu3) secondary building units featuring planar nine-membered Cu3N6 metallocycles with three peripheral pyridyl groups as connectors, which are further linked by CuX or Cu2X2 motifs to generate single- or double-strand chains. Interestingly, the Cu(I) atoms within the Cu3 units in 1-5 behave as coordinatively unsaturated pi-acid centers to contact soft halide/pseudohalide X atoms of CuX and Cu2X2 motifs, which lead to novel sandwich substructures of [(Cu3)(Cu2X2)(Cu 3)] (X = Br, I, and SCN) in 2-4. In addition, both the pi-acid [Cu3]···X contacts and intertrimer Cu···Cu interactions contribute to the one-dimensional (1D) double-strand and 2D/3D supramolecular structures of 1-5. All of these complexes exhibit high thermostability and bright solid-state phosphorescence upon exposure to UV radiation at room temperature. The emissions arise from the mixtures of metal-centered charge transfer, metal to ligand charge transfer, and halide-to-ligand charge transfer excited states, and can be tuned by intermolecular pi-acid [Cu3]···halide/ pseudohalide contacts.
