series of trifluoromethylated and bis(trifluoromethylated) precursors and monomers for bridge substituted trifluoromethylated poly(p-phenylenevinylene) (PPV) is reported. These monomers were prepared in several steps from terephthaldicarboxaldehyde and they contain symmetrical and unsymmetrical combinations of leaving groups and/or polarizers, including chlorides, sulfoxides, sulphones, tosylates and S-methyl
