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.

The lowest energy structures of neutral and charged copper oxide clusters were determined using primarily the B3LYP/LANL2DZ model chemistry. For n ? 4, the clusters are nonplanar. Selected electronic properties including atomization energies, ionization energies, electron affinities, and Bader charges were calculated and examined as a function of n.

In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system. COA of Formula: CCuNS, Name is Cuprous thiocyanate, COA of Formula: CCuNS, molecular formula is CCuNS. In a article，once mentioned of COA of Formula: CCuNS

Three small molecules (SMs) (DR3TSBDT, DR3TBDTT, and DRBDT-TT) were used as the front cell donor materials for highly efficient tandem OSCs which ensured both high open-circuit voltages and current density. The SM:PC71BM single-junction cell was fabricated with a structure of ITO/CuSCN/SM:PC71BM/ETL-1/Al. A thin layer of CuSCN processed from dimethyl sulfi de solution was spin-cast on top of precleaned ITO substrates and annealed in air at 120C for 10 minutes. or DR3TBDTT:PC71BM, chloroform was used for solvent vapor annealing. The tandem OSCs based on DR3TBDTT and DRBDT-TT also showed high PCEs of 10.73% and 10.43%, respectively. However, the overall open-circuit voltages is a little lower than the sum of open-circuit voltages of the subcells, suggesting a suboptimal contact at active layer/intermediate layer interface. A higher PCE would be obtained if the ICLs would be further optimized. All these demonstrate that the monodisperse SMs could perform as promising donor materials for high-performance tandem solar cells.

The development of effective and stable hole transporting materials (HTMs) is very important for achieving high-performance planar perovskite solar cells (PSCs). Herein, copper salts (cuprous thiocyanate (CuSCN) or cuprous iodide (CuI)) doped 2,2,7,7-tetrakis(N,N-di-p-methoxyphenylamine)-9,9-spirobifluorene (spiro-OMeTAD) based on a solution processing as the HTM in PSCs is demonstrated. The incorporation of CuSCN (or CuI) realizes a p-type doping with efficient charge transfer complex, which results in improved film conductivity and hole mobility in spiro-OMeTAD:CuSCN (or CuI) composite films. As a result, the PCE is largely improved from 14.82% to 18.02% due to obvious enhancements in the cell parameters of short-circuit current density and fill factor. Besides the HTM role, the composite film can suppress the film aggregation and crystallization of spiro-OMeTAD films with reduced pinholes and voids, which slows down the perovskite decomposition by avoiding the moisture infiltration to some extent. The finding in this work provides a simple method to improve the efficiency and stability of planar perovskite solar cells.

Inorganic p-type copper(I) thiocyanate (CuSCN) hole-transporting material (HTM) belongs to a promising class of compounds integral for the future commercialization of perovskite solar cells (PSCs). However, deposition of high-quality CuSCN films is a challenge for fabricating n-i-p planar PSCs. Here we demonstrate pinhole-free and ultrasmooth CuSCN films with high crystallinities and uniform coverage via delayed annealing treatment at 100 C, which can effectively optimize the interfacial contact between the perovskite absorber and the electrode for efficient charge transport. A satisfactory efficiency of 13.31% is achieved from CuSCN-based n-i-p planar PSC. In addition, due to the superior transparency of p-type CuSCN HTMs, it is also possible to prepare bifacial semitransparent n-i-p planar PSCs, which eventually permits a maximum efficiency of 12.47% and 8.74% for the front and rear illumination, respectively. The low-temperature process developed in this work is also beneficial for those applications such as flexible and tandem solar cells on heat-sensitive substrates.

Synthetic Route of 1111-67-7In an article, authors is Li, Dan, once mentioned the new application about Synthetic Route of 1111-67-7.

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).
