A series of thiophene-based conjugated microporous polymers （ThPOPs） have been synthesized on the basis of ferric chloride-catalyzed oxidative coupling polymerization of muRi-thienyl monomers. The structures of ThPOPs were confirmed via solid-state t3C CP/MAS NMR spectroscopy and Fourier-transform infrared spectroscopy. The ThPOPs possess high porosities and their high Brunauer-Emmett-Teller specific surface area results vary between 350 and 1320mZg . The presence of abundant ultra-micronores at 0.50-0.63 nm allows ThPOPs efficient gas （carbon dioxide, methane, and hydrogen） adsorption.

The oxidative polymerization of aryl sulfoxides provides a novel polysulfo-nium compound, poly(methylsulfonio-1,4-phenylenethio-1,4-phenylene cation) in quantita-tive yield. The polymerization proceeds efficiently in an acidic solution under atmosphericconditions. Oxygen, chemical and electrochemical oxidations are available. Vanadyl acety-lacetonate and cerium ammonium nitrate act as an effective catalyst for the oxygen ox-idative polymerization. The polymerization mechanism involves multielectron oxidation ofthe sulfides followed by successive electrophilic substitution. The resulting polyarylenesul-fonium cations are useful as a soluble precursor for the synthesis of high molecular weight(M_w>10~5) poly(thio arylne)s.
