摘要：

Three-dimensionally continuous ionic nanochannels have been developed by imidazolium-based ionic liquids and amphiphilic molecules having a diethanolamine moiety. Co-organisation of these two components into liquid-crystalline bicontinuous cubic phases leads to the formation of the 3D nanochannels. The induction of bicontinuous cubic phases is observed for the combination of an ionic liquid, 1-( 2-methoxyethyl)-3-methylimidazolium bromide, and a diethanolamine derivative, N-{3-[N', N'-bis(2-hydroxyethyl) aminopropyl]}-3,4-didodecyloxy benzoylamide. Compatibility enhanced by intermolecular interactions between the imidazoliums and the diethanolamine moiety plays an important role for the co-organisation of the two components. The three-dimensionally continuous ionic nanochannels function as efficient transportation pathways for ions. The material design using bicontinuous cubic liquid-crystalline structures will offer an opportunity for the development in the field of nanochannel material science.
