Photocatalytic Hydrogen Production Using a Red-Absorbing Ir(III) Co(III) Dyad

The synthesis of a Ir(III) - Co(III) dyad with vectorial electron transfer afforded a novel supramolecular system that photocatalytically produces hydrogen in a range extending from the blue region of the spectrum to the red region with higher turnover number and frequency compared to other bimetallic dyads.
