Outline of Final Research Achievements |
A wide variety of non-silica-based hybrid mesoporous materials have been successfully synthesized by the molecular design of phosphonate compounds that are useful for addition of functions and adjustment of reactivity to starting metal source. Towards the variation of organic groups within the frameworks, the design comparable to periodic mesoporous organosilica type materials is in sight. A mesoporous aluminum organophosphonate containing bipyridine linker was also realized as the final target of this study. For extending inorganic components, the precise design by considering the integer ratio of metal to phosphonate units was very important, imaging an isomorphous substitution to other metal unit to propose a methodology for controlling from hydrophobic surface to hydrophilic one in the molecular scale.

Academic Significance and Societal Importance of the Research Achievements |
金属ホスホン酸塩のメソポーラス構造化へ挑戦してきた結果として、多種多様な非シリカ系ハイブリッド型メソポーラス材料の合成法が蓄積されてきた。親水性/疎水性を分子スケールで調整した表面構造を有するナノ空間を設計することの学術的意義は化学反応に毎に相応しい環境が提供できることにある。例えば、溶媒を使用しない化学反応が実現できれば、分離プロセスに要するエネルギーの削減や環境負荷の高い化学物質の使用量低減等、社会的意義は大きい。
