Rapid Preparation of Silsesquioxane-Based Ionic Liquids.
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".
