The real nature of the mechanism of bipolaron conduction in conducting polymers and the discussion as to whether the charging–discharging currents in these materials are of a capacitive or a redox nature are central questions in conducting polymer research. Here, a number of methyl endcapped thiophene oligomers are studied using cyclic voltammetry in order to provide some of the answers.
