Abstract

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.
