Redox chemistry of ruthenium porphyrins: evidence for internal electron transfer and the characterization of [RuIII(OEP+˙)] species

Abstract

An internal electron transfer process from ruthenium(II) to an octaethylporphyrin radical moiety is induced by changes in axial ligation, and the species formed by a two-electron oxidation of ruthenium(II) porphyrins is characterized as a ruthenium(III) porphyrin cation radical.
