Outline of Final Research Achievements

Room temperature ionic liquids (RT-ILs) containing cage-like oligosilsesquioxane (POSS) structures were successfully prepared by lowering the crystallinity of POSSs and eliminating their melting points. A POSS with a random distribution of the two types of ionic side-chain groups and POSSs with imidazolium salts having long alkyl side-chains were RT-ILs. Furthermore, cyclic oligosiloxanes containing an imidazolium salt and an ammonium salt in the side chains also showed the property of RT-IL.
