Reversible reductions and oxidations at separated potentials are possible electro‐chemically in the solid state up to the tetraanion and tetracation respectively in the case of sexiphenyl. However, at room temperature and depending on the electrode potential the formation of more or less strongly cross‐linked polymer chains is observed during the oxidation. In addition, the measurements prove that the characteristic current plateaus in the voltammograms of conductive polymers are attributable to faradaic redox processes.
