| Outline of Final Research Achievements |
Efficient separation of oxygen and nitrogen, which have similar molecular sizes, from their mixture, air, is one of the important separation techniques. In this study, redox-active compounds were immobilized in the pores of a metal-organic framework (MOF) composed of metal ions and organic ligands. It was shown that MOF introduced with ferrocene as redox-active substance improved O2/N2 selectivity and O2 adsorption sites were formed in the MOF nanopores.

| Academic Significance and Societal Importance of the Research Achievements |
分子サイズがよく似た酸素と窒素をその混合気体である空気から効率的に分離することができれば、燃焼用酸素や医療用酸素を供給する技術を提供できる。さらに、生体内のヘモグロビンが酸素分子を運搬するような機能を無機系材料で模倣できれば、高効率な分離プロセスへの展開のみならず、ナノ空間や界面を利用したエネルギーデバイスへの応用展開が拓ける。本研究課題の成果は、人工ヘモグロビン型の分離機能材料の設計指針を示す一助となる。
