Recently, there has been increasing attention on the design of nanostructured materials having gyroid structures due to their unique three-dimensionally ordered structures. In this paper, bicontinuous cubic liquid crystal, one of representative materials that form gyroid structure, is discussed. There have been only a small number of researches on liquid-crystalline molecules exhibiting thermotropic bicontinuous cubic phases, and therefore it is difficult to design bicontinuous cubic liquid crystals. We have succeeded in overcoming the difficulty by introducing designability of ionic liquids into liquid crystal design. In this paper, we describe self-organizing ionic liquids that show bicontinuous cubic liquid-crystalline phases. Furthermore, their potential application as novel nanochannel materials is described.
