Porous organic polymer containing Tro <spacing diaeresis> ger's base skeleton and crown ether for cycloaddition of CO 2 and efficient iodine vapor adsorption

A wide range of templating reagents containing crown ether-based Tro <spacing diaeresis>ger's base structure and coordinating of various co-catalysts were synthesized by polymerization, and characterized using various analytic techniques. Their catalytic performance for CO 2 conversion and adsorption properties for iodine vapor were examined. Delightfully, after CETB-X recognized with HBr, all exhibited excellent catalytic activity in the presence of cetyltrimethylammonium bromide. The best-performing catalyst could convert CO 2 into cyclic carbonate with a yield of 93.1% under optimal reaction conditions. Furthermore, CETB-C 16 Br/C 16 N + Br - possessed excellent stability and substrate suitability with six times without any significant loss of catalytic activity. A preliminary kinetic study was investigated using CETB-C 16 Br/C 16 N + Br - and the activation energy has been calculated to be 41.51 kJ/mol. All of these polymers also exhibited iodine adsorption capacities above 3.0 g/g, with the most powerful adsorption reaching 4.68 g/g. Through kinetic simulations, the adsorption process was simulated as a pseudo-first-order kinetic model.
