A series of thiophene- and nitrogen-rich conjugated microporous polymers for efficient iodine and carbon dioxide capture

Two conjugated microporous polymers (CMPs) SNCMP-1 and SNCMP-2 with multiple active sites were synthesized using palladium(II) catalyzed coupling reaction; which exhibit excellent performance in volatile iodine capture with iodine adsorption values of 570 and 698 wt.%, respectively. In addition, SNCMP-1 and SNCMP-2 display outstanding CO2 adsorption capacity with uptake up to 3894 and 3878 mg g-1 at 70 bar and 323 K conditions, respectively.
