m- and p-Bis(diphenylene)propenylphenylacetylene (m-, p-8) were synthesized and polymerized with WCI6, moc15, and Rh catalyst, yielding solvent-soluble poly(phenylacetylene)s bearing a “π-conjugated bis(diphenylene)propenyl groups (m-, p-7a). The polymers gave their polyanion derivatives, which were electrolytically and chemically oxidized to yield the corresponding polyradicals (m-, p-7b). The polyradicals were chemically very stable due to the resonance stabilization of an unpaired electron whose spin concentration could be increased up to ca. 2 x 1023 spins per molar monomer unit. ESR spectroscopy suggested an antiferromagnetic interaction between unpaired electrons.
