Thiophene-based conjugated microporous polymers： synthesis, characterization and efficient gas storage

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 i...

Beschreibung
Zusammenfassung:	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.
