Organic solar cells that use only fullerenes as the photoactive material exhibit poor exciton-to-charge conversion efficiencies, resulting in low internal quantum efficiencies (IQE). However, the IQE can be greatly improved, when copper(I) thiocyanate (CuSCN) is used as a carrier-selective interlayer between the phenyl-C70-butyric acid methyl ester (PC70BM) layer and the anode. Efficiencies of ?5.4% have recently been reported for optimized CuSCN:PC70BM (1:3)-mesostructured heterojunctions, yet the reasons causing the efficiency boost remain unclear. Here, transient absorption (TA) spectroscopy is used to demonstrate that CuSCN does not only act as a carrier-selective electrode layer, but also facilitates fullerene exciton dissociation and hole transfer at the interface with PC70BM. While intrinsic charge generation in neat PC70BM films proceeds with low yield, hybrid films exhibit much improved exciton dissociation due to the presence of abundant interfaces. Triplet generation with a rate proportional to the product of singlet and charge concentrations is observed in neat PC70BM films, implying a charge?singlet spin exchange mechanism, while in hybrid films, this mechanism is absent and triplet formation is a consequence of nongeminate recombination of free charges. At low carrier concentrations, the fraction of charges outweighs the population of triplets, leading to respectable device efficiencies under one sun illumination.

Co(II), Ni(II), Cu(II) and Zn(II) complexes of bidentate Schiff bases derived from the condensation of 4-amino-5-mercapto-3-methyl/ethyl-1,2,4-triazole with 5-nitrofurfuraldehyde were synthesized and tested as antimicrobial agents. The Schiff bases and their metal complexes were characterized by elemental analyses, magnetic moment measurements, spectroscopic (IR, Electronic, 1H NMR, ESR) and thermogravimetric analyses. A square planar geometry for Cu(II) and octahedral geometry for Co(II), Ni(II) and Zn(II) complexes have been proposed. The presence of coordinated water in metal complexes was confirmed by thermal and IR data of the complexes. The Schiff bases and their metal complexes have been screened for antibacterial [Pseudomonas aeruginosa, Bacillus subtilis, Escherichia coli, Staphylococcus aureus] and antifungal activities [Aspergillus niger, A. flavus].

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

Application of a low-cost and efficient p-type inorganic hole-transporting material, copper thiocyanate (CuSCN), on mesoporous n-i-p-configurated perovskite-based devices was conducted in this study. Diethylsulfide was chosen for the preparation of precursor solution in order to deposit CuSCN layer on perovskite without degrading it. Topographical, elemental, and electrical characterizations of spin-coated CuSCN layers were performed using XRD, AFM, SEM, XPS, UPS, and UV-Vis studies. A power conversion efficiency exceeding 11.02% with an open-circuit voltage of 0.83 V was succeeded in the perovskite solar cells under full sun illumination. Low-temperature solution process used for the deposition of CuSCN and a fast solvent removal method allowed the creation of compact, highly conformal CuSCN layers that facilitate rapid carrier extraction and collection. The differences in series and recombination resistances for CuSCN-free and CuSCN-containing cells were also determined using impedance spectroscopy (IS) analysis. Moreover, the effect of TiO2 layer thickness on the cell performance was studied where these TiO2 layers were used not only for electron extraction and transportation, but also as hole blocking layer in perovskite solar cells. The impedance spectroscopy results were also consistent with the differently configurated cell performances. This work shows a well-defined n-i-p perovskite cell with optimized layers which utilize low-cost and abundant materials for photovoltaic applications.

Reaction of copper(I) thiocyanate with 1-ethyl-2-methyl-pyrazine in acetonitrile yields the two new coordination polymers catena[(mu 2-thiocyanato-N,S)-(1-ethyl-2-methylpyrazine-N)] copper(I)(I) and poly[(di-mu2-thiocyanato-N,S)-(mu2-1-ethyl-2-methyl- pyrazine-N,N?)] di-copper(I) (II). The crystal structure of I is composed of CuSCN double chains in which each copper atom is connected to two thiocyanate anions and two 1-ethyl-2-methyl-pyrazine ligands. In this compound only one nitrogen atom of the 1-ethyl-2-methyl-pyrazine ligand is involved in copper coordination. The crystal structure of II is composed of CuSCN layers that are connected by the N-donor ligands via mu-N,N? coordination into a three-dimensional coordination network. On heating the amine rich compound I loses half of the ligands and transforms into the amine-poorer compound II which occurs as an intermediate. Compound II decomposes on further heating to CuSCN. This reaction was investigated using simultaneous differential thermoanalysis and thermogravimetry coupled with mass spectroscopy and temperature dependent X-ray powder diffraction.

Abstract: Nanostructured inorganic?organic hybrid thin films of copper(I) thiocyanate (CuSCN) and 4-(N,N-dimethylamino)-4?-(N?-methyl)stilbazolium tosylate (DAST) were electrochemically self-assembled by adding DAST into methanolic bath containing Cu2+ and SCN? ions. Loading of the stilbazolium organic chromophore (DAS+) increased linearly on increasing DAST concentration, accompanied with changes of the film morphology, crystallographic orientation of CuSCN and transition from beta- to alpha-CuSCN. At low DAST concentrations, transport limited passive occlusion of DAS+ has been suggested with its diffusion coefficient of 1.25 × 10?6 cm2 s?1 in methanol at 298 K, while the loading receives kinetic limitation by the surface chemical reaction to yield definitive hybrid structures, resulting in unique ?hair comb? shape beta-CuSCN-DAST and ?nano-platelets? shape alpha-CuSCN-DAST hybrid structures. Both the inorganic and organic components are interconnected and bi-continuous, as the loaded DAS+ could be totally extracted by dimethylacetamide to leave porous skeleton of crystalline CuSCN, making them highly interesting for device applications.

Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. 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.

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.

This work focuses on the systematic investigation of the influences of pyrimidine-based thioether ligand geometries and counteranions on the overall molecular architectures. A N-containing heterocyclic dithioether ligand 2,6-bis-(2-pyrimidinesulfanylmethyl)pyridine (L1) and three structurally related isomeric bis(2-pyrimidinesulfanylmethyl)-benzene (L2-L4) ligands have been prepared. On the basis of the self-assembly of CuX (X = I, Br, Cl, SCN, or CN) and the four structurally related flexible dithioether ligands, we have synthesized and characterized 10 new metal-organic entities, Cu 4(L1)2I4 1, Cu4(L1) 2Br4 2, [Cu2(L2)2I 2·CH3CN]n 3, [Cu(L3)I]n 4, [Cu(L3)Br]n 5, [Cu(L3)CN]n 6, [Cu(L4)CN]n 7, [Cu2(L4)I2]n 8, [Cu2(L4)(SCN) 2]n 9, and {[Cu6I5(L4) 3](BF4)·H2O}n 10, by elemental analyses, IR spectroscopy, and X-ray crystallography. Single-crystal X-ray analyses show that the 10 Cu(I) complexes possess an increasing dimensionality from 0D (1 and 2) to 1D (3-5) to 2D (6-9) to 3D (10), which indicates that the ligand geometry takes an essential role in the framework formation of the Cu(I) complexes. The influence of counteranions and pi-pi weak interactions on the formation and dimensionality of these coordination polymers has also been explored. In addition, the photoluminescence properties of Cu(I) coordination polymers 4-10 in the solid state have been studied.

Regiocontrol of allylic alkylation reactions involving hard nucleophiles remains a significant challenge and continues to be an active area of research. The lack of general methods in which alpha-alkylation is favored underscores the need for the development of new processes for achieving this type of selectivity. We report that Cu(I) catalyzes the allylic substitution of phosphorothioate esters with excellent alpha-regioselectivity, regardless of the nature of the Grignard reagent that is used. To the best of our knowledge, the Cu-catalyzed allylic alkylation of phosphorothioate esters has never been described. We have also developed a simple protocol for inducing high alpha selectivity starting from secondary allylic halides. This is accomplished by using sodium phosphorothioates as an additive.

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 1111-67-7 is helpful to your research.
