Charge-selective disordered hetero-junctions were formed in evaporated In2S3 layers by diffusing at 200 C CuI from a CuSCN source. The thicknesses of In2S3 layers and diffusion times were varied between 5 and 80 nm and between 2 and 19 min, respectively. In some cases CuSCN layers were etched back with pyridine. Spectral and time-dependent surface photovoltage measurements were carried out in the capacitor arrangement. It was observed that a competing process of charge separation and relaxation was initiated together with the formation of the charge-selective In2S3/In2S3:Cu hetero-junction. Modulated SPV amplitude for different annealing times and thicknesses of the evaporated In2S3 layers. Copyright

p-CuSCN/n-ZnO rod array heterojunctions were electrodeposited with a weak basic (pH ?9) aqueous electrolyte solution. I-V characteristics showed the heterostructure had clear rectification, indicating good electrical contacts between ZnO rod arrays and the embedded CuSCN. The energy band model for the electrodeposition of CuSCN on ZnO rod arrays was proposed based on linear sweep voltammetric (LSV) measurements, which indicated that the electrodeposition process was the prior growth of CuSCN on bare ZnO rods according to a conduction process, followed by compact filling in the gaps of the arrays based on the thermal activation mechanism of surface states. The diode properties of the heterojunctions revealed that although deposition was dominated by thermal activation mechanism of surface states, the electrodeposition should be performed at a lower temperature in order to reach fine filling of the gaps of ZnO rod arrays.

Electric Literature of 1111-67-7, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. In an article, authors is Bowmaker, Graham A., once mentioned the application of Electric Literature of 1111-67-7, Name is Cuprous thiocyanate,molecular formula is CCuNS, is a conventional compound.

Copper(I) thiocyanate derivatives were prepared by the reaction of CuNCS with pyridine (py) and tertiary monophosphine ligands [PR3 in general; in detail: PPh3, triphenylphosphine, P(4-FPh)3, tris(4-fluorophenyl)phosphine)], as well as the potentially bidentate ligand diphenyl(2-pyridyl)phosphine (PPh2py). Mechanochemical methods were used in some cases to investigate stoichieometries that were not easily accessible by conventional solution syntheses. Three forms of the resulting adducts of CuNCS/PR3/py-base (1:3-n:n) stoichiometry-all containing four-coordinate copper(I) atoms and monodentate N-thiocyanate groups-were confirmed crystallographically. Mononuclear arrays are defined for [(PPh2py)3-n(py)nCuNCS], n = 0, 1, 2, the monodentate thiocyanate being N-coordinated in all; two polymorphs are observed for the n = 2 complex, both crystallizing in monoclinic P21 (Z = 2) cells with similar cell dimensions, but with aromatic components eclipsed about the Cu-P bond in the PPh3 complex, and staggered in the PPh2py complex. Bridging thiocyanate groups are found in the 1:1:1 CuNCS/PPh2py/2-methylpyridine (mpy) and P(4-FPh)3/mpy complexes, wherein centrosymmetric dimers with eight-membered central rings are obtained: [(R3P)(mpy)Cu(NCS)2Cu(PR3)(mpy)], as is also the case in the parent 1:2 CuNCS/PPh2py adduct [(pyPh2P)2Cu(NCS)2Cu(PPh2py)2]. For the 1:1:1 CuNCS/P(4-FPh)3/py and PPh3/Brmpy (Brmpy = 3-bromo-4-methylpyridine) adducts, and, likely, CuNCS/PPh2py/py (1:1:1), single-stranded polymers of the form [?Cu(NCS)(PR3)(py-base)(Cu)?](?|?) with linearly bridging NCS ligands were obtained. Some derivatives, representative of all forms, display medium to strong green to blue luminescence when excited with radiation at 365 nm. The 31P CPMAS NMR spectroscopic data clearly differentiate the inequivalent phosphorus positions within each system, showing a wide range of 1J(31P,63/65Cu) values ranging from 965 Hz for [Cu(NCS)(PPh2py)3] to 1540 Hz for dimeric [(4-FPh)3P(mpy)Cu(NCS)2Cu(P(4-FPh)3)(mpy)], reflecting the large variations in the Cu-P bond length.

The gamma-selective allylation of catalytic and stoichiometric alkylzinc-cuprates have been kinetically studied. The reactivity profiles generated by allylation reactions of n-butylzinc chloride catalyzed by CuX compounds (X = I, Br, Cl, CN, SCN) and also catalyzed by n-butylzinc-copper reagents and di n-butylzinc-copper reagents were evaluated. Reactivity profiles for allylation of stoichiometric n-butylzinc-copper reagents and di n-butylzinc-copper reagents were also prepared. All CuX compounds have been screened for the preparation of Grignard reagent derived n-butylzinc-copper reagents and di n-butylzinc-copper reagents. The evaluation of the profiles indicates that the active catalyst might be RCu(X)ZnCl and also to some degree, R2CuZnCl · ZnClX, which both could favor formation of gamma-product. All data supports the reductive elimination of sigma-allyl Cu (III) complex formed at vinylic terminal to give gamma-allylated product with a quite slow isomerization to sigma-allyl Cu (III) complex formed at allylic terminal to give alpha-allylated product. In the allylation mechanism of zinc cuprates, the role of counter ion, ZnCl+ has been discussed.

A method is found to significantly improve the p-type conductivity of CuSCN modified by incorporating triethylamine coordinated Cu(II) sites in its structure. It is done by mixing triethylamine hydrothiocyanate with CuSCN in propyl sulfide solution and allowing it to stand still in the dark for a few weeks in a closed sample tube. XRD and SEM analyses point to the modification of the CuSCN material. The Hall effect measurements clearly show a significant enhancement of hole concentration and hence of p-type conductivity. A maximum conductivity of 1.42 S m?1 is achieved for the structurally modified CuSCN compared to that of 0.01 S m?1 for ordinary CuSCN. AC impedance analysis of solid-state dye-sensitized solar cells based on this material clearly shows the reduction of bulk resistance of the cell with the use of modified CuSCN. This decrease in resistance has been attributed to the enhancement of conductivity and better pore filing of modified CuSCN inside the TiO2 matrix. As such, the solar cell performance gradually increases to an optimum value beyond which it decreases. The best result obtained for conversion efficiency is 3.4% at AM 1.5, which is a 41.8% enhancement from the best reported value for a dye-sensitized solid-state solar cell using CuSCN as a hole conducting material. The best efficiency value obtained is 14 times higher than that obtained for the dye-sensitized solid-state solar cell made with ordinary CuSCN.

Application 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.

We have synthesized novel metal organic hybrid mixed compounds of bis (acetylacetonato kappa-O, O?) [zinc(ii)/copper(ii)]. Taking C10H14O4Zn0.7Cu0.3 (Z0.7C0.3AA) as an example, the crystals are composed of Z0.7C0.3AA units and uncoordinated water molecules. Single-crystal X-ray diffraction results show that the complex Z0.7C0.3AA crystallizes in the monoclinic system, space group P21/n. The unit cell dimensions are a = 10.329(4) A, b = 4.6947(18) A, and c = 11.369(4) A; the angles are alpha = 90, beta = 91.881(6), and gamma = 90, the volume is 551.0(4) A3, and Z = 2. In this process, the M(ii) ions of Zn and Cu mix and occupy the centers of symmetrical structural units, which are coordinated to two ligands. The measured bond lengths and angles of O-M-O vary with the ratio of metal species over the entire series of the complexes synthesized. The chemistry of the as-synthesized compounds has been characterized using infrared spectroscopy, mass spectroscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy analysis, and the morphology of the products has been characterized using scanning electron microscopy. The thermal decomposition of the Z0.7C0.3AA composites measured by thermogravimetric analysis suggests that these complexes are volatile. The thermal characteristics of these complexes make them attractive precursors for metal organic chemical vapor deposition.
