Outline of Final Research Achievements

Two-component self-assembly of photopolymerizable zwitterionic molecule and acids such as benzenesulfonic acid and protic ionic liquids provided the hexagonal columnar liquid-crystalline phases. In-situ photopolymerization allowed for the construction of self-standing high-proton conductive polymer films. We revealed that the LC nanostructured films exhibited higher proton conduction with lower activation energy than those of amorphous films.
In addition, we demonstrated that the Bronsted base/acid complexes consisting of imidazole derivative with long alkyl chains and various acids such as benzenesulfonic acid formed the columnar, bicontinuous cubic, and smectic LC phases by simply changing the mixing ratio.

Academic Significance and Societal Importance of the Research Achievements

本研究では、高分子型燃料電池に資する新規のプロトン伝導ナノチャンネル構造を有する高分子フィルム材料の開発に成功し、ナノ構造の形成が伝導性を高めるという新現象を見出した。また、ブレンステッド酸塩基対形成を液晶材料設計に導入する学術的に新しいアプローチによって、従来設計では困難な双連続キュービック液晶構造を容易に構築することが可能になった。本研究で開発したイオン活性液晶は、燃料電池応用だけでなく、触媒膜、ガス分離膜、水処理膜、アクチュエータなど最先端材料・素子に展開できるため、社会的意義がある。
