Photochemical Co2 Reduction With Mononuclear And Dinuclear Rhenium Catalysts Bearing A Pendant Anthracene Chromophore

A series of anthracene-substituted mononuclear and dinuclear rhenium complexes have been studied for photocatalytic CO2 reduction. The effects on catalytic activity of one versus two covalently-linked active sites, their relative proximity to one another, and the pendant organic chromophore are discussed.
