Abstract: A series of novel bidentate ligands of fluoro phenanthrolines were designed and synthesized, which could formulate a series of heteroleptic copper photosensitizers CP1~CP4 with Cu(MeCN)4PF6 and Xantphos as P ligand. The photosensitive activities of this copper complex were researched in water reduction system, and the turnover number (TON) of hydrogen evolution was up to 896. The absorption spectrum and fluorescence emission spectrum of the copper complexes indicated the good stability in solution. The oxidation quenching is the main quenching pathway in water reduction system, which was confirmed by the fluorescence quenching experiments. Moreover, a preliminary explanation and discussion of the structure-activity relationship and the mechanism of photocatalytic hydrogen evolution from water were carried out. |
