Quality Control of Cuprous thiocyanate. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate

Three pillared-layered inorganic-organic hybrid polymers, namely, [Cu2(4,4?-Hbpt)(SCN)2]n (1), [Cd(4,4?-Hbpt)(SCN)2]n (2), and [Cd(4,4?-Hbpt)(SCN)2·CH3CN]n (3) were synthesized via layer diffusion methods. In all three complexes, there exist 2-D neutral wave-like d10 metal thiocyanate layers (for 1, [Cu2(SCN)2]n, and for 2 and 3, [Cd(SCN)2]n) with (4, 4) topology, which are further connected by bidentate 4,4?-Hbpt ligands to form 3-D structures with the primitive cubic topology. The results of photoluminescence and thermogravimetric analyses indicate that the three complexes are good candidates as luminescent materials. This paper provides a strategy to synthesize a novel family of pillared-layered inorganic-organic hybrid polymers constructed with layered d10 metal thiocyanate layers and conjugated organic spacers at the molecular engineering level, as well as the discovery of new patterns of crystallization at the crystal engineering level.

Most of the high performance in perovskite solar cells (PSCs) have only been achieved with two organic hole transporting materials: 2,2?,7,7?-tetrakis(N,N-di-p-methoxyphenylamine)-9,9-spirobifluorene (Spiro-OMeTAD) and poly(triarylamine) (PTAA), but their high cost and low stability caused by the hygroscopic dopant greatly hinder the commercialization of PSCs. One effective alternative to address this problem is to utilize inexpensive inorganic hole transporting layer (i-HTL), but obtaining high efficiency via i-HTLs has remained a challenge. Herein, a well-designed inorganic?organic double HTL is constructed by introducing an ultrathin polymer layer dithiophene-benzene (DTB) between CuSCN and Au contact. This strategy not only enhances the hole extraction efficiency through the formation of cascaded energy levels, but also prevents the degradation of CuSCN caused by the reaction between CuSCN and Au electrode. Furthermore, the CuSCN layer also promotes the formation of a pinhole-free and compact DTB over layer in the CuSCN/DTB structure. Consequently, the PSCs fabricated with this CuSCN/DTB layer achieves the power conversion efficiency of 22.0% (certified: 21.7%), which is among the top efficiencies for PSCs based on dopant-free HTLs. Moreover, the fabricated PSCs exhibit high light stability under more than 1000 h of light illumination and excellent environmental stability at high temperature (85 C) or high relative humidity (>60% RH).

Synthetic Route of 1111-67-7, Healthcare careers for chemists are once again largely based in laboratories, although increasingly there is opportunity to work at the point of care, helping with patient investigation. Mentioned the application of 1111-67-7, Name is Cuprous thiocyanate.

The low temperature fast solution annealing (FSA) concept is used for the deposition of perovskite film. In this simple method, a spin coated perovskite film was subsequently immersed into hot (80 C) anti-solvent chlorobenzene. For this solution annealing process, sophisticated lab facility is not required to prevent humidity and moisture. Performance of devices, fabricated by FSA method using methylammonium lead iodide (MAPbI3) perovskite with two different hole transport materials (HTMs), was investigated. The power conversion efficiency (PCE) obtained for copper(I) thiocyanate (CuSCN) and 2,2?,7,7?-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9?-spirobifluorene (Spiro-OMeTAD) HTMs were 10.02% and 12.10%, respectively.

Seven conductive radical cation salts based on MDSe-TSF (methylenediselenotetraselenafulvalene) have been synthesized by electrocrystallization in the presence of Cl-, Br-, I3-, I2Br-, PF6-, ClO4-, and Cu(NCS)2- counter anions. The crystal appearances of these salts fairly depend on the anions employed. X-ray crystallographic analyses have revealed that the PF6 and ClO4 salts in the shape of brown thin plates adopt the theta-type structures characterized by the herringbone arrangement of donor stacks, whereas the Cl and Br salts in the shape of black thick plates favor the kappa-type structures with the orthogonal arrangement of donor dimers. Regardless of different crystal appearances or crystal packing patterns, all these salts show high conductivity (> 102 S cm-1) at room temperature and retain metallic properties down to 4.2 K. Of them, the Br salt shows a weak but distinct diamagnetic shielding signal below 4 K in the dc magnetization measurement under zero-field-cooled (ZFC) condition, suggesting a sign of superconductivity. The band calculations of both PF6 and Br salts demonstrate closed Fermi surfaces indicative of two-dimensional molecular conductors.

The synthesis and crystal structure elucidation of two novel polymeric copper(II) complexes has led us to propose a mechanism for the formation of 2-picolinic acid (pic) from di-2-pyridyl ketone (dpk) and benzoic acid from acetophenone. During studies into the interaction of copper ions with the dpk-acetophenone system, two complexes Na2(NCS)2(H 2O)[Cu(pic)2] (1) and Na2(H2O) 2[Cu(pic)2(NCS)2] (2) which contain pic coordinated to copper were isolated. The occurrence of (1) and (2) has led us to consider the Baeyer-Villiger rearrangement as a possible mechanism for the formation of (1) and (2).

Application of 1317-39-1, Name is Copper(I) oxide, Application of 1317-39-1, molecular formula is Cu2O. In a article，once mentioned of Application of 1317-39-1

The photoelectrochemical properties of electrodeposited Cu2O in aqueous solutions were investigated. The material showed long term stability under illumination at negative potentials. The diffusion length of electrons in the as-deposited material was of the order of 10-100 nm. We did not observe photocathodic reduction of water. The efficiencies for the reduction of oxygen and the methylviologen cation at these electrodes were surprisingly high. This suggests that, in conjunction with a suitable redox system, electrodeposited Cu2O could be a promising material as a p-type photoelectrode in an electrochemical photovoltaic cell.
