Ionicliquids have attracted a considerable attention as the next generation electrolytes for energy devices. We have developed new free‐standing and nanostructuredpolymerfilms in which ionicliquids are confined into one‐dimensionally ordered nanochannels. These polymerfilms have been obtained by photopolymerization of hydrogen‐bonded supramolecularcolumnarliquid‐crystalline self‐assemblies of
