Abstract: A novel poly(p-phenylenevinylene) related copolymer was synthesized by Wittig reaction. The corresponding cationic conjugated polymer was successfully obtained via a post-polymerization approach. On the basis of 1H NMR spectra, it was found that this phenyl-substituted PPV related copolymer is of 30% cis-vinylic linkage. The quenching effect of Fe(CN)64- on the cationic PPV derivative was studied, and a downward Stern-Volmer curve was found.

Key words: Conjugated polyelectrolytes, Quenching effect, Poly(p-phenylenevinylene)
