Two new copper(I) complexes of di-2-pyridyl ketone (DPK); [(DPK)H][CuI2] (1) and [(DPK)H][(Cu{NCS)2] (2) have been prepared and characterized by spectroscopic and crystallographic methods. Both complexes are colored and exhibit very broad and strong MLCT bands in the visible region. The IR spectra of these complexes are measured and discussed. The structure determination of complex 1 shows that it consists of discrete [(DPK)H]+ cation contains N-H···N hydrogen bonds, and polymeric [CuI2]- anion. In the anion, each copper atom is in a distorted tetrahedral environment with Cu-I bond lengths from 2.570(4) to 3.072(4) A?. The structure of complex 2, which is similar to 1, features uncoordinated N-protonated di-2-pyridyl ketone cations and corrugated layers of [Cu(NCS)2](n), in which the copper atom is in a distorted tetrahedral CuS2N2 chromophore; Cu-N bond lengths are 1.954(2) and 1.958(2) A?, and Cu-S distances are 2.4120(8) and 2.4501(7) A?.

Inorganic hole?transporting materials (HTMs) are a promising class of compounds for improving the long-term stability of perovskite solar cells. In this study, copper(I) thiocyanate (CuSCN) has been applied as an HTM in planar-structured thin film perovskite solar cells based on methylammonium lead(II) triiodide. A common obstacle associated with the deposition of inorganic HTMs in perovskite-based solar cell devices is the damaging effect of polar solvents, required during the solution-processed deposition step, on the underlying perovskite film. Here we describe a novel fabrication method that allows the deposition of a CuCSN layer on perovskite film, achieving a maximum power conversion efficiency of 9.6%. The magnitude of J-V hysteresis is found to be strongly dependent on the HTM used, with the phenomenon being much more prevalent in the CuSCN- and spiro-OMeTAD-based devices compared to CuI-based devices. Interestingly, CuSCN and CuI showed significantly different J-V hysteresis behaviors despite their similar physicochemical properties. Further characterization by open circuit voltage decay (OCVD) measurements revealed that the relaxation of the perovskite polarization depends on the light intensity and the adjacent HTM layer. We propose that the stronger J-V hysteresis in CuSCN compared to CuI is a result of defects generated during the deposition process and possible degradation at the material interfaces while other possibilities are also discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 1111-67-7, you can also check out more blogs aboutReference of 1111-67-7

Semiconducting copper(I) thiocyanate (CuSCN) is actively studied for electronic and optoelectronic applications. Although various kinds of CuSCN-based transistors are reported, these devices suffer from low charge carrier mobility of about 0.01?0.1 cm2 V?1 s?1. Here, ion gel electrolyte consisting of network polymer and ionic liquid is used as a high capacitance gate insulator to achieve high performance CuSCN-based electrolyte-gated transistors (CuSCN-EGTs) with low operation voltage below 1 V. 30 nm thick CuSCN semiconductor film can be formed by a simple solution process with a low processing temperature (?100 C) that is directly applicable to flexible plastic substrates. By doping copper iodide to the CuSCN semiconductor, device performance including drain current and charge carrier mobility of the CuSCN EGT can be improved significantly. The measured charge carrier mobility of ?0.3 cm2 V?1 s?1 is the highest among the reported CuSCN transistors using various gate insulators. These CuSCN-EGTs also display good operation stability under continuous quasistatic external gate voltage sweeps. Such superior electrical performance and versatile processability of ion gel?gated CuSCN transistors make them suitable for use in complimentary circuits and large-area flexible electronics.

CuO and Cu2O nano/microparticles with pure phases have been synthesized from the same precursor by a hydrothermal method. Hydrothermal heating of Cu(OAc)2 produced CuO at 125 C whereas pure Cu2O was obtained at 175 C. Heating at 150 C gave a CuO/Cu2O mixture. In contrast, Cu(acac)2 produced only Cu2O at all three temperatures. The pure phases of Cu2O and CuO nano/microparticles were confirmed by PXRD and XPS characterization. The mechanistic studies indicate that decomposition of the organic anion/ligand of the Cu-precursor played a key role in the formation of CuO/Cu2O nano/microparticles from Cu(OAc)2/Cu(acac)2. FE-SEM studies revealed the formation of CuO with a microsphere morphology (125 C) and a micro-cup for Cu2O at 175 C. Nanowires and micron-sized elliptical cylinders were observed for Cu2O synthesized from Cu(acac)2. However, calcination of Cu(OAc)2, Cu(acac)2 and Cu(NO3)2 at 500 C produced crystalline CuO nano/microparticles with various sizes and morphologies. Further, CuO nano/microparticles investigated for industrially important aromatic nitro to amine conversion showed morphology dependent nitro group reduction. Smaller spherical CuO nano/microparticles obtained from Cu(acac)2 exhibited the highest catalytic activity. The reusability studies indicate that CuO nano/microparticles can be used for up to six cycles. Thus we have presented a simple method to synthesize Cu2O or CuO from the same precursor and demonstrated the morphology dependent catalytic activity of CuO nano/microparticles.

Inorganic CsPbBr3 perovskite solar cell (PSC) has attracted much attention owing to its outstanding air and thermal stability and low cost manufacture process. Crystalline TiO2 (c-TiO2) has been widely used as electron-transporting layer (ETL) material for inorganic CsPbBr3 PSC. However, c-TiO2 requires high-temperature (>450 C) fabrication process which impedes the application of flexible inorganic CsPbBr3 PSC and its low electron mobility further limits the performance enhancement. Herein, we prepared novel amorphous Nb2O5 (a-Nb2O5) ETL through a facile room-temperature sputtering method for inorganic planar CsPbBr3 PSC. The PSC with a-Nb2O5 ETL has gained a champion efficiency of 5.74%, which is higher than that of the PSC (5.12% or 4.67%) based on crystalline Nb2O5 (c-Nb2O5) ETL or c-TiO2 ETL by high-temperature (500 C) annealing. The improved photovoltaic characteristic for CsPbBr3 PSC with a-Nb2O5 ETL may be ascribed to its suitable work function, high optical transmittance, low charge recombination at the a-Nb2O5/CsPbBr3 interface and the superior crystallinity of CsPbBr3 film deposited on a-Nb2O5 ETL. Moreover, the a-Nb2O5-based CsPbBr3 PSC without encapsulation exhibits a good long-term stability in ambient atmosphere. This work offers a new research direction for preparing high-performance inorganic PSC.

The cyclization reactions of alkynes have become one of the most important and useful methodologies for the preparation of heterocycles. To this end, the association between alkynes and nitrogen sources are versatile substrates for the synthesis of triazole derivatives. The improvement in the synthesis of triazoles by the use of copper catalysts in cycloaddition reactions, as well as the significant advances obtained with the use of other transition metals, such as gold, iridium, iron, nickel, ruthenium, samarium, silver, and zinc, to promote the cyclization of alkynes and nitrogen sources are addressed in this review. Furthermore, there has been a significant interest in recent years in developing simple, clean, non-toxic, cost-effective and eco-friendly protocols. In this sense, the reaction of alkynes with nitrogen sources, in the complete absence of transition metals, reaches many of these requirements becoming a good alternative to the synthesis of triazoles. For this reason, the last topic of this review deals with the synthesis of triazoles using alkynes and nitrogen sources under transition metal-free conditions.

The Cu(phac)2 complex was synthesized by the reaction of copper(II) acetate with acetylacetone phenylhydrazone (Hphac), and its crystal structure was established by X-ray diffraction: space group P21/c, a = 11.173(3) A, b = 8.267(2) A, c = 12.633(4) A, beta = 115.01(3), V = 1057.5(5) A3, Z = 4, R1 = 0.0476. The crystal structure of Cu(phac)2 consists of the centrosymmetrical mononuclear molecules. The central copper(II) ion is coordinated by two oxygen atoms and two nitrogen atoms of two acetylacetone phenylhydrazone ligands. The Cu(phac)2 molecules are linked in layers parallel to the Oyz plane. The oxygen atoms of the ketone fragment are involved in intermolecular bonding, which completes the coordination sphere of the central copper(II) ion to a substantially elongated octahedron. The thermal stability of the Cu(phac)2 complex was estimated under nitrogen at atmospheric pressure and in vacuo.
