Efficient chem. fixation of carbon dioxide (CO2) into valuable fine chems. requires porous materials with highly active catalytic centers. Herein, multifunctional imidazolium based hypercrosslinked ionic polymers with versatile functional groups (sulfonic, hydroxyl, amino, carboxyl, and alkyl group), abundant microporosity and high ionic site d. were constructed in a two-step solvothermal route including free-radical copolymerization of divinylbenzene (DVB), 4-vinylbenzyl chloride (VBC) and imidazolium bromide ionic liquids (ILs) and successive Friedel-Crafts alkylation based hypercrosslinkage. The resultant hydroxyl-functional ionic polymer demonstrated promising performances in selective adsorption and conversion of CO2 via cycloaddition with epoxide. High yield associating with large turnover number (TON) and turnover frequency (TOF), stable reusability and well substrate compatibility were achieved, affording an efficient metal-free heterogeneous catalyst for CO2 fixation. The full microporous structure resulted in CO2 enrichment around the robust hydroxyl-functional ionic sites, showing a synergistic effect to promote CO2 transformation.
