The crystal structures of two mono(dpyam)copper(II) complexes, [Cu(dpyam)(NO2)2] (1) and [Cu(dpyam)(H2O)2(SO4)] (2) and two dithiocyanate compounds containing bis(dpyam)copper(II) units, [Cu(dpyam)2(NCS)](SCN)·0.5DMSO (3) and [Cu(d- pyam)2(SCN)2] (4) have been determined by X-ray crystallography. The second orthorhombic form of the monomeric Cu(II) complex 1 was obtained by the reaction of di-2-pyridylamine (dpyam) with CuCl and NaNO2 in water-methanol solution. Each copper(II) ion in 1 exhibits a tetrahedrally-distorted square base of the CuN2O2 chromophore, with off-the-z-axis coordinated nitrito groups weakly bound in approximately axial positions. Complex 2 is an example of a polymeric copper(II) derivative containing the bidentate bridging sulfate ligand in the long-bonded axial positions. Each copper(II) ion in 2 shows an elongated tetragonal octahedral stereochemistry. The CuN4N? chromophore of 3 involves a square-based pyramidal structure, slightly distorted towards a trigonal bipyramidal stereochemistry, tau = 0.13. One of the SCN- anions is bonded to the copper(II) ion via the N atom in the axial position of the square pyramid. Complex 4 is centrosymmetric and octahedrally elongated, with the SCN- anions coordinating in axial positions via the S atom. The structures of complexes 1-4 and their ESR and electronic reflectance spectra are compared with those of related complexes.

Solid-state dye-sensitized photovoltaic cells have been fabricated with TiO2 as the electron conductor and CuSCN as the hole conductor. These cells involve the nanoscale mixing of crystalline n-type and p-type semiconductors in films that are more than 100 times thicker than the individual n- and p-type domains. Charge transport and field distribution in this kind of material are as yet unexplored. We have used photocurrent and photovoltage transients, combined with variation in the layer thickness, to examine the limiting factors in charge transport and recombination. Charge transport (t 1/2 a¿¿ 200 I¼s) is found to be similar to that in dye-sensitized electrolyte cells. Recombination at Voc (t1/2 a¿¿ 150 I¼s) is 10 times faster than in electrolyte cells, and recombination at short circuit (t1/2 a¿¿ 450 I¼s) is 100 times faster. In the solid-state cells, the similarity of the charge transport and recombination rates results in a low fill factor, and photocurrent losses, both important limiting factors of the efficiency. A simple model is given, and suggestions are made for improvements in efficiency.

Reference of 13395-16-9, Chemistry is a science major with cience and engineering. The main research on the structure and performance of functional materials.Mentioned the application of 13395-16-9, Name is Bis(acetylacetone)copper.

The kinetics and mechanism of copper film growth from the reactions of bis(acetylacetonato)copper(II), bis(hexafluoroacetylacetonato)copper(II), and (vinyltrimethylsilane)(hexafluoroacetylacetonato)copper(I) (Cu(hfac)(vtms)) with copper single crystal surfaces were investigated. Experiments were performed using vibrational spectroscopy (reflection infrared and high-resolution electron energy loss spectroscopies) as well as mass spectrometry (temperature-programmed desorption and integrated desorption mass spectrometries). Both ligand desorption and dissociation were observed upon pyrolysis of these molecules under ultra-high-vacuum conditions. We demonstrate that adsorbed beta-diketonate ligands decompose in a stepwise fashion at temperatures above ?375 K to yield adsorbed CF3 and ketenylidene (?C-C?O) intermediates. These further decompose above ?500 K to leave surface carbon, a major contaminant in copper films grown from CuII beta-diketonates. Clean films can be grown from the pyrolysis of Cu(hfac)(vtms) at pressures above 10-5 Torr, however. The implications of our results relative to the mechanism of copper film growth at elevated pressures are also discussed.

The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 1111-67-7, Name is Cuprous thiocyanate, belongs to copper-catalyst compound, is a common compound. COA of Formula: CCuNSIn an article, once mentioned the new application about 1111-67-7.

Solution-processed CuSCN serving as hole transport, electron reflecting layer (HTL, ERL) and Cu dopant source for CdSe/CdTe thin-film solar has demonstrated high power conversion efficiency (PCE) of ~17%. Two types of solvent, diethyl sulfide (DES) and aqueous ammonia (NH4OH), are explored to deposit CuSCN on CdTe, and both can enhance the performance of CdSe/CdTe solar cells. However, NH4OH solvent is less toxicity, leading to a smoother surface than DES solvent, enabling the deposition of ultra-thin CuSCN layer and avoiding the high cost of DES. Temperature-dependent current-voltage (J-V-T) and capacitance-voltage (C-V-T) measurements reveal that the use of CuSCN HTL increases hole concentration in CdTe absorber and significantly reduces back-contact barrier height. High power conversion efficiency is achievable with the optimal thickness of the CuSCN layer. Our results demonstrate solution-processed CuSCN HTL for enhancing the efficiency and reducing the cost of CdTe thin-film solar cells.
