Abstract
Redox‐modified polythiophenes exhibiting the highest mixed‐valence conductivities of any polymer containing a pendant redox group are reported. The ordering of the polymer, in which the backbone has been oxidized to a bipolaron conducting state and the redox sites have been reduced to a mixed‐valence conducting state, encourages inter‐site hopping and results in the high conductivities. Electron interactions are shown not have an influence on the conduction.
