Electric Literature of 1235481-90-9, Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 1235481-90-9, Name is P7C3-A20, SMILES is COC1=CC(NCC(F)CN2C3=C(C4=C2C=CC(Br)=C4)C=C(Br)C=C3)=CC=C1, belongs to benzoxazole compound. In a article, author is Wang, Dan-Dan, introduce new discover of the category.
Four new three-coordinate cuprous complexes with a CuN2P core, 1-QBO, 2-Phen, 3-MePBO, 4-QBI, were designed and synthesized by utilizing a steric hindrance of phosphine ligand o-Anisyl(3)P [QBO = 2-(2′-quinolyl)benzoxazole, Phen = 1,10-Phenanthroline, MePBO = 5-methyl-2-(2′-pyridyl)-benzoxazole, QBI = 2(2′-quinolyl)benzimidazole, o-Anisyl(3)P = tri(2-methoxyphenyl)-phosphine]. As a counterpart to 1-QBO, a four-coordinate complex 5-QBOP2 has also been synthesized with a CuN2P2 core. All complexes were characterized by single-crystal X-ray diffraction, spectroscopic analysis (IR, UV-Vis), elemental analysis, and photoluminescence study. Single-crystal X-ray diffraction revealed that complexes 1-4 all adopt trigonal CuN2P coordination geometry with one phosphine and one diimine ligand. Their UV-Vis absorption spectra exhibit concentration dependences of absorption edge shift. Time-dependent density functional theory (TD-DFT) calculations reveal that their S-1 states and the peak transition states can be mainly assigned as ligand-ligand & metal-ligand charge transfer (L’LCT + MLCT) and intra-ligand charge transfer (ILCT) states, respectively. It is noteworthy that all three-coordinate complexes 1-4 do not display obvious photoluminescence (PL), whereas the PL of four-coordinate complex 5 is turned on by an extra coordination of a phosphine ligand to 1. This PL complex has also been synthesized and characterized as 5-QBOP2 from 1-QBO. This model of three-coordinate to four-coordinate change with PL turn-on behavior could be used for sensing volatile organic compounds (VOCs). (C) 2019 Elsevier Ltd. All rights reserved.
