| Outline of Final Research Achievements |
In this study, we aimed to construct porous materials by integrating molecular porous graphene and to link their unique structures to unique functions. While working on the development of a new molecular porous graphene, we succeeded in elucidating the integrated structure in a crystalline solid by applying various cutting-edge structural analysis methods. In particular, we interested in the structure of a reduced state from the viewpoint of a battery negative electrode material and succeeded in analyzing the crystal structure of a chemically reduced state. Furthermore, we were able to discover a wide range of functions for the obtained solid materials, including applications as negative electrode materials for lithium-ion batteries and as gas adsorption materials.

| Academic Significance and Societal Importance of the Research Achievements |
分子性孔あきグラフェンは比較的新しい化合物群であり、中心部位に空孔を有する「グラフェン」のような分子、という独特の構造的特徴からその物性・機能に興味が持たれている。一方で、その分子量はC60フラーレンを超えることが多く、有機化合物としては大きな構造であるために、特に結晶性固体状態での構造解析が困難である。本研究で、困難な構造解析を実証し、さらに独特な構造に由来する特異機能を解明したことで、この新しい化合物群の固体をどう取り扱ったらよいか学術的なアプローチを示し、材料としての有用性を社会的に示すことができた。
