Photocatalytic reduction of nicotinamide co-factor by perylene sensitized Rh(III) complexes

We report a catalytically active intramolecular photocatalyst, which combines a perylene photosensitizer and a Rh(III) catalyst. Spectroscopic studies reveal the formation of a charge-separated perylene radical cation-Rh(II) intermediate that results in a catalytically active species in the presence of protons
