Giereth, Robin;Mengele, Alexander K.;Frey, Wolfgang;Kloss, Marvin;Steffen, Andreas;Karnahl, Michael;Tschierlei, Stefanie published 《Copper(I) Phosphinooxazoline Complexes: Impact of the Ligand Substitution and Steric Demand on the Electrochemical and Photophysical Properties》 in 2020. The article was appeared in 《Chemistry – A European Journal》. They have made some progress in their research.Recommanded Product: (S)-2-(2-(Diphenylphosphanyl)phenyl)-4-isobutyl-4,5-dihydrooxazole The article mentions the following:
Seven homoleptic CuI complexes based on hetero-bidentate PN̂ ligands were synthesized and comprehensively characterized. To study structure-property relations, the type, size, number and configuration of substituents at the phosphinooxazoline (phox) ligands were systematically varied. To this end, a combination of x-ray diffraction, NMR spectroscopy, steady-state absorption and emission spectroscopy, time-resolved emission spectroscopy, quenching experiments and cyclic voltammetry was used to assess the photophys. and electrochem. properties. Also, time-dependent d. functional theory calculations were applied to also analyze the excited state structures and characteristics. Surprisingly, a strong dependency on the chirality of the resp. PN̂ ligand was found, whereas the specific kind and size of the different substituents has only a minor impact on the properties in solution Most importantly, all complexes except C3 are photostable in solution and show fully reversible redox processes. Sacrificial reductants were applied to demonstrate a successful electron transfer upon light irradiation These properties render this class of photosensitizers as potential candidates for solar energy conversion issues. And (S)-2-(2-(Diphenylphosphanyl)phenyl)-4-isobutyl-4,5-dihydrooxazole (cas: 167693-62-1) was used in the research process.
(S)-2-(2-(Diphenylphosphanyl)phenyl)-4-isobutyl-4,5-dihydrooxazole(cas: 167693-62-1) is a compound of chiral-phosphine-ligands. At present, the synthesis of new chiral phosphines designed specifically for nucleophilic organocatalysis remains a significant challenge.Recommanded Product: (S)-2-(2-(Diphenylphosphanyl)phenyl)-4-isobutyl-4,5-dihydrooxazole
