Outline of Final Research Achievements

In this study, we designed and synthesized novel covalent organic frameworks, which have been focus of much attention in recent years. It was shown that electronic and photophysical properties can be controlled by changing the molecular structure. We also investigated the formation of assembled structures, and succeeded in creating layered and sheet structures of triazine network polymers. Tuning the slight structural differences in the molecules, the ordered structure was realized despite they conventionally have random network structure. The organic conjugated skeleton materials prepared by this study functioned as electrocatalysts expected to be applied to fuel cells and other devices.

Academic Significance and Societal Importance of the Research Achievements

電解反応を促進する電極触媒は、白金等レアメタルが用いられるため、代替材料の開発が希求されている。有機共役骨格材料は、資源制約がなく分子構造を自在に制御可能なことから、魅力的な代替材料である。本研究では、酸素還元電極触媒として機能する新たな二次元性有機共役骨格を作製し、分子構造と性能の関係を考察することで、より高性能な有機電極触媒を設計するための方針を示した。すなわち、貴金属に依存しないエネルギー変換技術の発展に貢献するものといえる。
