摘要：Porous ionic polymers have demonstrated great potential for high-performance separation by the merits of their unique molecular recognition,but the preparation of anion-functionalized ionic polymers for the separation of bioactive molecules with highly similar structures remains a ***,through the facile Friedel-Crafts alkylation between benzylimidazole ionic liquids(ILs)and crosslinkers,several anion-functionalized hypercrosslinked ionic porous polymers(HIPs)are reported,which are well decorated with strongly basic carboxylate anions as well as feature tubular morphology and excellent thermal *** adsorption capacity(103.6 mg g^(−1) for tocopherol homologues)and selectivity(S_(βγ/α),4.26;S_(δ/α),3.19)for bioactive compounds with high structural similarity have been realized,superior to those of commercial adsorbents,hypercrosslinked polymer without ILs,and HIPs with common *** study manifests a new synthetic strategy and rational molecular design for functionalized adsorbents,as well as offers new opportunities to enable high-performance separation.
