New discoveries in chemical research and development in 2021. In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 1235481-90-9, Name is P7C3-A20, molecular formula is C22H19Br2FN2O. In an article, author is Xu, Yuling,once mentioned of 1235481-90-9, SDS of cas: 1235481-90-9.
N-heterocyclic chelating and triphenylphosphine ligands react with cuprous halide to form a variety of copper(I) complexes, namely, mononuclear [Cu(PBO)(PPh3)Br](CH2Cl2)-C-. (1) and [Cu(PBM)(PPh3)I] (2) (PBO=2-(2-Pyridyl)benzoxazole, PBM=2-(2-Pyridyl)benzimidazole, PPh3=triphenylphosphine) and tetranuclear [Cu-4((2)-I)(2)((3)-I)(2)(PPh3)(4)](.)2CH(2)Cl(2) (3) have been synthesized and characterized. Complexes 1 and 2 are basically alike; both of them are mononuclear and four-coordinated, possessing a slightly distorted trigonal pyramidal geometry. Complex 3 is tetranuclear and the coordination numbers of the two copper(I) atoms are three and four, Cu(1) forming an approximate trigonal planar coordination environment, while Cu(2) is a slightly distorted trigonal pyramidal geometry, resulting in a distorted chair-like conformation. Complexes 1 and 2 are emissive in the solid state at ambient temperature, with the maxima at 552 and 602nm, respectively, due to a MLCT excited state. Moreover, complex 3 manifests promising heterogeneous catalytic activities for the degradation of methylene blue (MB), with degradation efficiency of 99% under ambient light.
