Formation of a long-lived radical pair in a Sn(IV) porphyrin-di(L-tyrosinato) conjugate driven by proton-coupled electron-transfer

Abstract

The novel conjugate 1, featuring two L-tyrosinato residues axially coordinated to the tin centre of a Sn(IV)-tetraphenylporphyrin, is reported as first example of a supramolecular dyad for photochemical PCET. Noteworthy, excitation of 1 in the presence of a suitable base is followed by photoinduced PCET leading to a radical pair state with surprisingly long lifetime.
