具有热致液晶(LC)双连续立方相的室温离子液体形成了三维互联的纳米离子通道网络。这些LC离子液体是一类具有自组织纳米结构的新型离子导电材料。离子液体具有扇形的嵌段分子结构，由两个不相容的分子部分组成：聚焦点的铵部分和亲脂性的三(烷氧基)苯基部分。我们证明了在LC双连续立方相中无取向的材料的离子电导率高于在LC柱状相中观察到的离子电导率。
Three-dimensionally interconnected nano-ion channel networks are formed by room-temperature ionic liquids exhibiting thermotropic liquid-crystalline (LC) bicontinuous cubic phases. These LC ionic liquids are a new family of ion-conductive materials with selforganized nanostructures. The ionic liquids have fan-shaped block molecular structures composed of two immiscible molecular parts: the ammonium moiety at the focal point and the lipophilic tris(alkyloxy)phenyl part. We demonstrate that the ionic conductivities of the materials that are alignment free in the LC bicontinuous cubic phases are higher than those observed in the LC columnar phases.
