Abstract
Boronic acid-functionalized porous polycarbazoles (PCBA-1 and PCBA-2) which possess special functions as well as permanent porosity have been synthesized by oxidative coupling polymerization, followed by characterization of their chemical structure and porosities. The Brunauer–Emmett–Teller (BET) specific surface area value scope of PCBA-1 and PCBA-2 is from 868 to 768 m2 g−1 and the related dominant pore sizes are centered at about 1.0 nm. PCBA-1 and PCBA-2 exhibit potential adsorption for vapor solvent and small gas molecules. Their adsorption capacity for methanol measured at saturated vapor pressure and room temperature is 534 and 430 mg g−1, respectively. They also show moderate uptake capacity (15.3 and 14.0 wt%) for CO2 at 1.0 bar and 273 K. Also, the obtained porous polymers as effective heterogeneous catalysts can promote transformation of 1,2-diols into α-hydroxy ketones accordingly by selective oxidation.
