The cycloaddition reaction of CO2 with various epoxides to generate cyclic carbonates is one the most promising and efficient approaches for fixation. Typical imidazolium-based ionic liquids possessing electrophilic cations nucleophilic halogen anions have been identified as excellent environmentally friendly candidates synergistically activating convert . Therefore, feasible construction a series imidazolium-functionalized organic cationic polymers can bridge gap between homogeneous heterogeneous catalysis, thereby obtaining highly selective adsorption simultaneous conversion ability. This Review describes recent advancements made regard design synthesis this type polymeric networks having imidazolium functionality. They are considered an outstanding catalyst epoxides. Based on perspective from building blocks polymers, focus mainly lies how introduce imidazole units into material backbone via covalent linking approach incorporate other active sites capable and/or such materials.

Development of efficient solid catalysts for catalytic conversion dilute CO2 is extreme importance carbon capture and utilization. We report the synthesis bifunctional polymers co-incorporated with porphyrin-Zn as Lewis acid sites Br– nucleophiles cycloaddition epoxides in this work. It was found that Br–/Zn ratio has a volcano relation activity reaction, indicating synergy effect between nucleophiles. The turnover frequency (TOF) polymer more than four-fold physical mixture tetrabutylammonium bromide porphyrin-Zn-incorporated polymer, implying enhanced cooperation network. optimized afforded 99% conversion, selectivity, TOF high 12,000 h–1 propylene oxide, which among most active ever reported. Furthermore, could efficiently catalyze epichlorohydrin (7.5% balanced by N2) even under ambient conditions, demonstrating its potential application industrial-scale production.

Though N-heterocyclic carbenes (NHCs) have emerged as diverse and powerful discrete functional molecules in pharmaceutics, nanotechnology, catalysis over decades, the heterogenization of NHCs their precursors for broader applications porous materials, like metal-organic frameworks (MOFs), coordination polymers (PCPs), covalent-organic (COFs), organic (POPs), organometallic cages (POMCs) was not extensively studied until last ten years. By de novo or post-synthetic modification (PSM) methods, myriads containing building blocks were designed integrated into MOFs, PCPs, COFs, POPs POMCs to form various structures porosities. Functionalisation with significantly expands scope potential materials by tuning pore surface chemical/physical properties, providing active sites binding guest substrates realizing recyclability. In this review, we summarise discuss recent progress on synthetic structural features, promising functionalised materials. At end, a brief perspective encouraging future prospects challenges contemporary field is presented. This review will serve guide researchers design synthesize more novel precursors.
