Abstract
AbstractTwo new thiophene‐based conjugated microporous polymers (BTCMP‐1 and BTCMP‐2) were synthesized by cross‐coupling polycondensation reaction of dithiophene derivatives, 1,4‐phenylenediboronic acid and 1,2,4,5‐tetrafluorobenzene. BTCMP‐1 and BTCMP‐2 display good physicochemical stability and outstanding CO2 adsorption capacity (648 and 289 mg/g at 50 bar and 318 K, respectively). In addition, BTCMP‐1 and BTCMP‐2 exhibit high iodine adsorption of 480 and 284 wt%, respectively. BTCMP‐1 has relatively loose accumulation and good porosity, which leads to higher iodine adsorption value of BTCMP‐1 than that of BTCMP‐2. The obtained thiophene‐based conjugated microporous polymers are ideal materials for iodine capture and carbon dioxide capture.
