Abstract
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.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
