Porous organic polymer containing Tröger's base skeleton and crown ether for cycloaddition of CO2 and efficient iodine vapor adsorption.

[Display omitted] • Porous organic polymers containing Tröger's base skeleton and crown ether were fabricated using template-induced method. • The microstructure is influenced by templates and TB-CE-KIs/HBr showed high catalytic efficiency of CO 2 fixation. • The synergistic mechanism has been proved in terms of experimental results and calculation of dynamics. • All materials showed excellent iodine vapor adsorption. • The adsorption process was simulated as pseudo-first-order kinetic model. A wide range of templating reagents containing crown ether-based Tröger'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. [ABSTRACT FROM AUTHOR]
