Microstructures, optical and photovoltaic properties of CH3NH3PbI3(1-x)Clx perovskite films with copper(I) thiocyanate (CuSCN) additive were investigated. The CuSCN-added CH3NH3PbI3(1-x)Clx films were prepared by a hot air blow-assisted spin-coating method. Current density-voltage characteristics of the photovoltaic device using the CuSCN-added CH3NH3PbI3(1-x)Clx light-absorbing layer showed increases in short-circuit current density, open-circuit voltage, which resulted in increase in the conversion efficiency. Microstructure analysis showed that the crystal structure of the CuSCN-added CH3NH3PbI3(1-x)Clx was a pseudocubic system. From these results, partial substitutions of Pb2+ and anions (I- and Cl-) by Cu ions (Cu+ and Cu2+) and SCN-, respectively, are considered to occur in the CuSCN-added CH3NH3PbI3(1-x)Clx films. Based on the obtained results, reaction mechanisms of the CH3NH3PbI3(1-x)Clx films with and without CuSCN additive were discussed.

Application In Synthesis of Cuprous thiocyanateIn an article, once mentioned the new application about 1111-67-7.

Background: Resuscitation promoting factors (Rpfs) are the proteins involved in the process of reactivation of the dormant cells of mycobacteria. Recently a new class of nitrophenylthiocyanates (NPTs), capable of inhibiting the biological and enzymatic activities of Rpfs has been discovered. In the current study the inhibitory properties of the compounds containing both nitro and thiocyanate groups alongside with the compounds with the modified number and different spatial location of the substituents are compared. Methods: New benzoylphenyl thiocyanates alongside with nitrophenylthiocyanates were tested in the enzymatic assay of bacterial peptidoglycan hydrolysis as well as against strains of several actinobacteria (Mycobacterium smegmatis, Mycobacterium tuberculosis) on in-lab developed models of resuscitation of the dormant forms. Results: Introduction of the additional nitro and thiocyanate groups to the benzophenone scaffold did not influence the inhibitory activity of the compounds. Removal of the nitro groups analogously did not impair the functional properties of the molecules. Among the tested compounds two molecules without nitro group: 3-benzoylphenyl thiocyanate and 4-benzoylphenyl thiocyanate demonstrated the maximum activity in both enzymatic assay (inhibition of the Rpf-mediated peptidoglycan hydrolysis) and in the resuscitation assay of the dormant M. tuberculosis cells. Conclusions: The current study demonstrates dispensability of the nitro group in the NPT’s structure for inhibition of the enzymatic and biological activities of the Rpf protein molecules. These findings provide new prospects in anti-TB drug discovery especially in finding of molecular scaffolds effective for the latent infection treatment.

In an article, once mentioned the application of Related Products of 1111-67-7, Name is Cuprous thiocyanate,molecular formula is CCuNS, is a conventional compound. this article was the specific content is as follows.

Inorganic charge transporting materials offer numerous advantages over their organic counterparts, including high charge carrier mobility, stability, simple preparation, and low cost, and have been studied for perovskite optoelectronic devices. However, the majority of these materials strongly quench perovskite luminescence, which is detrimental to the performance of perovskite light-emitting devices. To overcome this and obtain good quality perovskite films, an organic interlayer modified with UV ozone is used. The effects of the UV ozone treatment on the energetics and chemical structures of the organic interlayer are examined. On the basis of this strategy, we fabricate perovskite light-emitting devices that contain a cuprous thiocyanate hole injection layer, which exhibit an improved external quantum efficiency of 10.2% and greater operational stability when compared with the devices that contain a conducting-polymer hole injection layer.

Introducing a new discovery about 1317-39-1, Name is Copper(I) oxide, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.

The unrestricted Hartree-Fock (UHF) and hybrid-density functional theory (DFT) calculations have been carried out for the metal oxides such as copper oxides and nickel oxides. In order to elucidate magnetic properties of the species, the effective exchange integrals (Jab) have been obtained by the total energy difference between the highest and lowest spin states in several computational schemes with and without spin projection. The mixing ratios of the exchange correlation functionals in the hybrid DFT method have been reoptimized so as to reproduce the Jab values for strongly correlated oxides. The natural orbital analysis has also been performed for elucidation of symmetry and occupation numbers of the magnetic orbitals. From these calculated results, we discuss characteristics of the magnetic interactions for metal oxides in the strong correlation regime.

A new method is proposed for measuring the antioxidant capacity by electron spin resonance spectroscopy based on the loss of electron spin resonance signal after Cu2+ is reduced to Cu+ with antioxidant. Cu+ was removed by precipitation in the presence of SCN-. The remaining Cu2+ was coordinated with diethyldithiocarbamate, extracted into n-butanol and determined by electron spin resonance spectrometry. Eight standards widely used in antioxidant capacity determination, including Trolox, ascorbic acid, ferulic acid, rutin, caffeic acid, quercetin, chlorogenic acid, and gallic acid were investigated. The standard curves for determining the eight standards were plotted, and results showed that the linear regression correlation coefficients were all high enough (r > 0.99). Trolox equivalent antioxidant capacity values for the antioxidant standards were calculated, and a good correlation (r > 0.94) between the values obtained by the present method and cupric reducing antioxidant capacity method was observed. The present method was applied to the analysis of real fruit samples and the evaluation of the antioxidant capacity of these fruits. (Graph Presented).
