Outline of Final Research Achievements

This study focused on the development of anhydrous proton conductors forming continuous nano-ionic channels by using self-assembly of liquid crystals. We have successfully prepared the following innovative ionic conductors: (1) anhydrous proton conductors forming one- and three-dimensional ionic channels by the complexation of zwitterionic liquid crystals and sulfonic acids; (2) anisotropic one- and two-dimensional proton conductors prepared by hydrogen-bond formation between diol-functionalized liquid crystals and protic salts; (3) anisotropic conductive polymer films by photopolymerization of the columnar liquid crystals composed of diol compounds containing photopolymerizable diene groups and ionic liquids.
