Synthesis and conductivity of poly acene quinone radical polymers

Polymers with conductivities from 8.6 × 10⁰ to 7.3 × 10^?6 (ω cm)^?1 at 2–12 kbar were prepared by zinc-chloride-catalyzed condensation of polycyclic aromatic hydrocarbons, heterocycles, and quinones with pyromellitic dianhydride, tetrabromophthalic anhydride, and tetrachlorophthalic anhydride at 450°C. These materials are stable in air and exhibit strong electroactive character without addition of oxidizing or reducing agents (dopants).
