Polymeric tetraphenylbenzidine materials show two independent overlapping conductivity regimes (II and III on the conductivity profile in figure) upon electrochemical doping. Conductivity in these systems is attributed to one‐electron hopping between the isoenergetic states of the two localized redox pairs. Bipolaronic charge transport was not observed.
