离子液体作为新一代的能源电解质受到了广泛的关注。我们已经开发了新的独立和纳米结构的聚合物膜，其中离子液体被限制在一维有序的纳米通道中。这些聚合物膜已经通过基于咪唑钥的离子液体和含有可聚合基团的楔形二醇化合物的氢键合的超分子柱状液晶自组装体的光聚合获得。在玻璃衬底上的柱状结构的宏观上的平行排列已经实现了通过施加机械剪切，并随后通过UV照射固定到聚合物膜中。该含离子液体的聚合物膜表现出比先前报道的通过共价型柱状液晶咪唑鎓盐的原位光聚合获得的一维聚合物膜更高的离子电导率。一维离子导电聚合物膜的非共价超分子方法导致导电性能的改善。© 2014 Wiley Periodicals，Inc.

Ionic liquids have attracted a considerable attention as the next generation electrolytes for energy devices. We have developed new free‐standing and nanostructured polymer films in which ionic liquids are confined into one‐dimensionally ordered nanochannels. These polymer films have been obtained by photopolymerization of hydrogen‐bonded supramolecular columnar liquid‐crystalline self‐assemblies of an imidazolium‐based ionic liquid and a wedge‐shaped diol compound containing polymerizable groups. The macroscopically parallel alignment of the columnar structures on a glass substrate has been achieved by the application of mechanical shearing, and subsequently fixed into polymer films by UV irradiation. This ionic liquid‐containing polymer film exhibits higher ionic conductivity than that of the previously reported one‐dimensional polymer film obtained byin situphotopolymerization of a covalent‐type columnar liquid‐crystalline imidazolium salt. The noncovalent supramolecular approach to one‐dimensionally ion‐conductive polymer films has led to improvement on conductive properties. © 2014 Wiley Periodicals, Inc. J. Polym.
