Herein we describe anhydrous proton transportation through 3D interconnected pathways formed by self-assembled molecular complexes. A thermotropic bicontinuous cubic (Cub(bi)) phase has been successfully obtained by mixing a wedge-shaped sulfobetaine with benzenesulfonic acid in different ratios. These ionic complexes exhibit the Cub(bi) phase in a wide range of temperatures, while the single zwitterionic compound shows only a columnar hexagonal phase, and benzenesulfonic acid is nonmesomorphic. Anhydrous proton conduction on the order of 10(-4) S cm(-1) has been achieved for the mixture in the Cub(bi) phase over 100 °C, which can be useful for the development of new electrolytes for the next generation of fuel cells.
在这里，我们描述了通过自组装分子配合物形成的 3D 相互连接的通道中的无水质子传输。通过以不同比例混合楔形磺基甜菜碱和苯磺酸，成功获得热致双连续立方（Cub(bi)）相。这些离子配合物在很宽的温度范围内表现出 Cub(bi)相，而单一的两性离子化合物仅显示柱状六方相，苯磺酸是非晶相的。在 Cub(bi)相中，混合物的无水质子传导率达到 10(-4) S cm(-1) 量级，超过 100°C，这对于开发下一代燃料电池的新型电解质可能是有用的。
