| Outline of Final Research Achievements |
O2@openC60 and NO@openC60, which were synthesized by a organic surgery chemistry, could be used for the investigation of chemical reaction within the nano-scale flask of endo-fullerene. The interaction between O2 (NO) and fullerene cage was clarified by electron spin resonance measurements. The fullerene cage gave certain disturbance toward the ground electronic wave function of endo-O2, or NO, resulting in the vanish of the axial symmetry of homo-diatomic molecule. In addition to the disturbance, the fullerene cage gave some shielding effect which prevents neighboring molecules from the inter-molecular interaction, then the the isolated-molecule properties were kept even in the condensed phase.

| Academic Significance and Societal Importance of the Research Achievements |
外科手術的有機化学合成法で酸素分子O2とNOラジカルがフラーレンケージC60に内包された分子(O2@openC60，NO@openC60)は，フラーレンC60をナノサイズ反応容器と見なすことが可能であり，凝集状態であっても孤立した分子の特性を保存することが確かめられた．このことで，フラーレンケージは反応容器として，ナノサイズ化学反応追跡のための反応場となり得ることを示せた．
