Three new hybrid ionic liquids (ILs) based on cage silsesquioxane (SQ) were rapidly prepared in high yields from octa(mercaptopropyl)silsesquioxane and 1-allyl-3-methylimidazolium salts (Br(-), BF4(-), PF6(-)) through the photochemical thiol-ene reaction. These SQ-based ILs exhibited low glass transition temperatures and good thermal stability. The unique amphiphilic nature of these hybrid ILs cause them to self-assemble into perfect vesicles with "yolk-shell" structures, in which cages formed the "yolk" due to their aggregation and outer anions formed the "shell".
通过光化学硫醇-烯反应，由八（巯基丙基）倍半硅氧烷和1-烯丙基-3-甲基咪唑鎓盐（Br⁻、BF₄⁻、PF₆⁻）以高产率快速制备了三种基于笼型倍半硅氧烷（SQ）的新型杂化离子液体（ILs）。这些基于SQ的离子液体表现出低玻璃化转变温度和良好的热稳定性。这些杂化离子液体独特的两亲性质使它们自组装成具有“蛋黄-壳”结构的完美囊泡，其中笼状物由于聚集形成“蛋黄”，外部阴离子形成“壳”。
