Rhenium(<scp>i</scp>) trinuclear rings as highly efficient redox photosensitizers for photocatalytic CO₂ reduction

Abstract

Trinuclear Re(<sc>i</sc>)-rings were applied as redox photosensitizers in visible light-driven CO₂ reduction in tandem with various catalysts, <italic>i.e.</italic>, Re(<sc>i</sc>)-, Ru(<sc>ii</sc>)- and Mn(<sc>i</sc>)-diimine metal complex. The quantum yields for the Ru(<sc>ii</sc>) and Mn(<sc>i</sc>) catalysts were the among highest reported.
