A series of thiophene-based conjugated microporous polymers(ThPOPs) have been synthesized on the basis of ferric chloride-catalyzed oxidative coupling polymerization of multi-thienyl monomers. The structures of ThPOPs were confirmed via solid-state 13 C 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 1320 m~2 g~(-1). The presence of abundant ultra-micropores at 0.50–0.63 nm allows ThPOPs efficient gas(carbon dioxide, methane, and hydrogen) adsorption.
