Two kinds of novel water soluble polyelectrolyte and organic soluble precursor polymers of poly(phenylene vinylene) with bromine substituted side chain were synthesized from tri-sulfonium salt monomer. The results showed that the sulfonium salt on the butoxy substituted side chain did not take part in the polymerization, thus the organic soluble precursor can be obtained at proper condition. Primarily photo-physics studies showed that the poly(phenylene vinylene) with bromine substituted side chain doped with C-60 had good photo-electric properties, The structure of the monomer and the precursor polymers were characterized by IR, UV-Vis, H-1 NMR, GPC and DSC.
