Zn-containing porphyrin as a biomimetic light-harvesting molecule for biocatalyzed artificial photosynthesis

Chem Commun (Camb). 2011 Oct 7;47(37):10227-9. doi: 10.1039/c1cc12222c. Epub 2011 Jul 11.

Abstract

Among the porphyrin molecules with different metal insertion sites and functional ligands, Zn-porphyrin most efficiently regenerates NADH through photo-induced electron transfer in the presence of [Cp*Rh(bpy)H(2)O](2+), a rhodium-based electron mediator. Photochemical regeneration of NADH by Zn-porphyrin is successfully coupled with redox enzymatic synthesis under dark state conditions.
