CONDUCTIVITY IN REDOX MODIFIED CONDUCTING POLYMERS - IN-SITU CONDUCTIVITY OF POLY(CYCLOPENTADITHIOPHENES) BEARING P-NITRO-PHENYL AND 4-N-METHYLPYRIDINIUM GROUPS

Communication: Redox-modified polythiophenes exhibiting the highest mi xed-valence conductivities of any polymer containing a pendant redox g roup 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 inte r-site hopping and results in the high conductivities. Electron intera ctions are shown not have an influence on the conduction.
