| Outline of Final Research Achievements |
The synthetic methods to create a large opening on fullerenes have been developped. A water molecule was encapsulated into the open-cage C60 derivative, and the opening was completely restored to afford H2O@C60 in a macro-scopic scale under the mild reaction conditions. To reallize an encapsulation of a large molecule, efficient way to create a larger opening was found by the reaction with nucleophilic oxidants, which was also applied to a precursor of azafullerenes, in which one of the carbon atoms in fullerene cages is replaced with a nitrogen atom. As another method to enlarge the opening, a sulfur atom was introduced on the rim of the openings. When this reaction was applied to an open-cage C60 derivative, a new open-cage C59S derivative was obtained in addition to the expected compound having a larger opening. Furthermore, when this reaction was applied to an open-cage C70 derivative, another new reaction was found to afford an open-cage C69S derivative.
