Satoshi Minakata and colleagues, Osaka University, Japan, prepared, isolated, and characterized an inclusion complex of [60]fullerene and organosilylated γ-cyclodextrin. 

The complex is highly soluble in nonpolar and weakly polar organic solvents, such as CHCl₃ or cyclohexane. It allows to separate C₆₀ from C₇₀, selective chemical functionalization of C₆₀, and solution-processed fabrication of a thin film of the complex.

Further research on the use and application of the complex is ongoing.
