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

Abstract

By selecting the building blocks with different active sites, 4-formylphenylboronic acid (FBA), 3,3′,5,5′-tetrabromo-2,2′-benzothiophene (DDT) and N,N′,N′′,N′′′-tetra(p-phenylene)para-phenylenediamine (TABD), two conjugated microporous polymers (CMPs), SNCMP-1 and SNCMP-2, with multiple active sites were synthesized via a palladium(II)-catalyzed coupling reaction. They exhibited excellent performances in volatile iodine capture with iodine adsorption values of 570 and 698 wt%, respectively. In addition, SNCMP-1 and SNCMP-2 displayed outstanding CO2 adsorption capacities with uptakes up to 3894 and 3878 mg g−1 at 70 bar and 323 K conditions, respectively.
