Importance of steric bulkiness of iridium photocatalysts with PNNP tetradentate ligands for CO2 reduction

A series of Ir complexes has been developed as multifunctional photocatalysts for CO2 reduction to give HCO2H selectively. The catalytic activities and photophysical properties vary widely across the series, and the bulky group insertion resulted in the formation of HCO2H and CO with the catalyst tu...

Description
Summary:A series of Ir complexes has been developed as multifunctional photocatalysts for CO2 reduction to give HCO2H selectively. The catalytic activities and photophysical properties vary widely across the series, and the bulky group insertion resulted in the formation of HCO2H and CO with the catalyst turnover number of >10 400.
