Coulombic effects in radical-cation-based high-spin polymers

Abstract

A comparison of the cyclic voltammetric behaviour of a high-spin polymer precursor having the local topology of a 3,4′-diaminobiphenyl with that of related oligomers shows that the hole–hole repulsion associated with the coextensive spin–spin distribution is < 0.2 V, a noticeable effect but not one large enough to explain the difficulty of doping these polymers.
