We show the preparation and functionalization of fan-shaped imidazolium and ammonium salts forming fluid columnar liquid-crystalline phases. Anisotropic ionic conductivities have been achieved by macroscopic alignment of the one-dimensional ion-conductive paths, which are formed through self-assembly and phase-segregation of the ionic and non-ionic moieties. We will discuss the relationships between their molecular structures, liquid crystalline properties, and ionic conductivities.
