Metal-Centered Photoinduced Electron Transfer Reduction of a Gold(III) Porphyrin Cation Linked with a Zinc Porphyrin to Produce a Long-Lived Charge-Separated State in Nonpolar Solvents

Metal-Centered Photoinduced Electron Transfer Reduction of a Gold(III) Porphyrin Cation Linked with a Zinc Porphyrin to Produce a Long-Lived Charge-Separated State in Nonpolar Solvents

Photoexcitation of an electron donor−acceptor linked dyad containing gold(III) and zinc(II) porphyrins (ZnPQ−AuIIIPQ+) results in electron transfer from the singlet excited state of ZnPQ to the metal center of AuPQ+ to produce the charge-separated state (ZnPQ•+−AuIIPQ) which has a long lifetime (10...

Zusammenfassung:Photoexcitation of an electron donor−acceptor linked dyad containing gold(III) and zinc(II) porphyrins (ZnPQ−AuIIIPQ+) results in electron transfer from the singlet excited state of ZnPQ to the metal center of AuPQ+ to produce the charge-separated state (ZnPQ•+−AuIIPQ) which has a long lifetime (10 μs) in nonpolar solvents such as cyclohexane and toluene.
