Unidirectional Transmembrane Photoinduced Electron Transfer with Artificial Metallopeptides.

ABSTRACT: The ability to drive unidirectional photoinduced electron transfer through an insulating lipid membrane is one of the most striking features of the thylakoid membrane, and recreating this property artificially is considered as one of the holy grails of artificial photosynthesis. Here, we report two artificial metallopeptides, WALP23-Re ₂ and WALP23-Ru ₂ , that were embedded in the membrane of dissymmetric liposomes containing an electron donor in the inner compartment and an electron acceptor in the bulk aqueous phase. Upon light irradiation under air, unidirectional electron transfer was observed from one side of the membrane to the other one with both metallopeptides. However, the mechanism of photoinduced electron transfer strongly depen
