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"
