摘要:
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 13C 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 1320m2g-1.The presence of abundant ultra-micropores at 0.50-0.63 nm allows ThPOPs efficient gas (carbon dioxide,methane,and hydrogen) adsorption.
