The rational integration of multiple functional components into a composite material could result in enhanced activity tailored for specific applications. Herein, imidazolium-based poly(ionic liquid)s (denoted as polyILs) have been confined into the metal–organic framework (MOF) material MIL-101 via in situ polymerization of encapsulated monomers. The resultant composite [email protected] exhibits good CO₂ capture capability that is beneficial for the catalysis of the cycloaddition of CO₂ with epoxides to form cyclic carbonates at subatmospheric pressure in the absence of any cocatalyst. The significantly enhanced activity of [email protected], compared to either MIL-101 or polyILs, is attributed to the synergistic effect among the good CO₂ enrichment capacity, the Lewis acid sites in the MOF, as well as the Lewis base sites in the polyILs.

将咪唑基聚离子液体掺入金属有机框架中以进行CO ₂捕集和转化

将多种功能成分合理地整合到复合材料中，可以增强针对特定应用量身定制的活动。本文中，通过包封单体的原位聚合，基于咪唑鎓的聚离子液体（表示为polyIL）被限制在金属有机骨架（MOF）材料MIL-101中。所得的复合物[电子邮件保护的]表现出良好的CO ₂捕获能力，这对于在不存在任何助催化剂的情况下在低于大气压的条件下催化环氧化物加成CO ₂与环氧化物催化形成环状碳酸酯是有利的。与MIL-101或polyIL相比，[电子邮件保护]的活动显着增强，这归因于良好的CO ₂之间的协同作用 富集能力，MOF中的Lewis酸性位点以及polyIL中的Lewis碱性位点。
