title: Supramolecular photocatalysts constructed with a photosensitizer unit with two tridentate ligands for CO2reduction.
abstract: New supramolecular photocatalysts comprising an asymmetric bis-tridentate Ru(ii) complex that functions as a photosensitizer and a Ru(ii) carbonyl complex as the catalyst were designed. The complexes photocatalyzed the reduction of CO2to CO or formic acid with high selectivity. The product distribution depended on the catalyst unit. CO and formic acid were the main products when using [Ru(BL)(Clbpy)(CO)]2+(BL = bridging ligand, Clbpy = 4,4'-dichloro-2,2'-bipyridine) and Ru(BL)(CO)2Cl2catalysts, respectively.
