摘要：

Transition metal complexes are an important class of molecular catalysts for CO2 photoreduction. Herein, we report a bis(terpyridine)Zn(II) complexes modified with anthryl groups. This Zn(II) complex is highly efficient for CO2 photoreduction with a TON of CO up to 585 and 96.2% selectivity, which is 10 times higher than that of its parent complex without any substituent modification. It is further revealed that such a significant enhancement of TON is due to the larger conjugated system of the modified Zn(II) complex, which stabilizes the proposed ligand-based radical anion. These results provide an efficient strategy to enhance the catalytic performance of a molecular catalyst by the ligand modification.
