Abstract: 2,5-Dimethoxybenzene-p-dichloromethyl sulphonium salt as the monomer of poly(2,5-dimethoxy-p-phenylene vinylene)was obtained with a yield over 75% through improved methoxylation, chloromethylation and sulphonization procedures from hydroquinone. The reaction conditions were studied in detail and the synthesized products in each step were confirmed by GC/MS and 1H NMR.

Key words: dimethoxybenzene-phenylene vinylene, Wessling synthesis, sulphonium salt monomer
