A highly electroactive polythiophene-metallophthalocyanine hybrid material was prepd. which exhibits cond. more than three orders of magnitude higher than that of know macrocycle-connected polymers. The triptycene-contg. phthalocyanine macrocycle monomers have electrochem. polymerizable thiophene moieties on alternating subunits which give nearly linear polymer backbone with the metal center in direct electronic communication with the conjugated polymer backbone. The electrochem. polymn. proceeds through oxidative coupling of pendant thiophenes. The cyclic voltammogram of the Ni complex polymer displays prominent features in the reductive region at -1.35 and -1.75 V assignable to the Ni redox and ligand-centered processes, resp. The polymer shows both metal-centered electroactivity and high cond. and the Ni redox wave does not contribute to the cond. [on SciFinder(R)]
