Synthetic routes to polyradicals are briefly reviewed; in addition the synthesis and electrochemical characterization of a novel anthraquinone derivatized thiophene monomer, 1-[4-(3-thienyl)butyl]2-anthraquinone carboxylate (I) is discussed. This monomer may be electropolymerized onto Pt in CH2Cl2 by successively more anodic potential sweeps from 0.0V, finally reaching a steady growth at a limit of +2.0V vs Ag+/0. Thhe voltammogram of the resulting conducting polymer displaysa polymer waves at Epa + 1.0 and Epc + 0.84V, and quinone waves at E0′ = -0.80 and -1.24V vs Ag.+/0 The polymer is active towards O2 reduction in pH7 buffered aqueous solution.
