Mixed-valence porphyrin π-cation radical derivatives: Electrochemical investigations

Abstract

The electrochemistry of [Cu(OEP)] and [Ni(OEP)] are compared with the mixed-valence π-cations [Cu(OEP) /2]2+ and [Ni(OEP) /2]2+. These electrochemical studies, carried out with cyclic voltammetry and hydrodynamic voltammetry, show that the mixed valence π-cations have distinct electrochemical properties, although the differences between the [M(OEP)]+/0 and [M(OEP) /2]2+/0 processes are subtle.
