Outline of Annual Research Achievements |
Porous materials possessing inherent pores are attractive for ion conduction across their nanopores. COFs can combine well-defined structure, tunable porosity and functionality, and excellent thermal and chemical stabilities, which are hardly obtained by using other porous materials. Recent advances have shown that COFs can provide a new platform for designing proton conducting materials. Especially, the long-range ordered one-dimensional channels of 2D COFs are suitable as proton conveyer and are important for improving the proton conductivity. I have designed mesoporous TPB-DMTP-COF and TAPB-DMPTA-COF for proton conduction based on phosphoric acid. The high pore volume of the two COFs enables the loading of proton carrier PA at high content. The proton conductivity of PA@TPB-DMPT-COF at 100 and 120 °C are the highest among porous materials. I have designed and synthesized large-pore TPB-TMDPDA-COF for proton conduction.Then introduced the proton carriers such as imidazole and triazole into the channel of the COFs. And the materials also have demonstrated excellent proton conductivity.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
平成29年度の研究では、細孔サイズの大きな共有結合性有機骨格構造体を系統的に合成し、1次元チャンネルサイズと伝導との相関を明らかにし、最適な細孔サイズを定めることを検討する。平成30年度の研究では、ヘキサゴナール構造以外に、四角や三角、菱形など様々なトポロジーを有する共有結合性有機骨格構造体を合成し、細孔トポロジーによる伝導機能の発現を検討する。

Strategy for Future Research Activity |
1. 四角や三角、菱形のトポロジーを有する一連の共有結合性有機骨格構造体を合成し、そのガス吸着特性を評価する。2. 優れた多孔性を有する共有結合性有機骨格構造体を選出し、イオンキャリアを導入して複合体を合成する。3. 伝導度を検討し、伝導活性化エネルギーを算出する。4. 構造と伝導との相関を明らかにし、最適な分子トポロジーを決める。
