Abstract
A novel metal-encapsulated fullerene compound wherein a side chain is introduced in a metal-encapsulated fullerene is provided. A metal-encapsulated fullerene compound represented by the following structural formula (1) is synthesized by causing a disilirane derivative or digermirane derivative having the following structural formula (2) to react with a metal-encapsulation fullerene so as to add functional groups to the fullerene. ##STR1## Herein, M is an encapsulated metal atom, m is an integer from 1 to 3, n is an even number from 28 to 200, and R is a t-butyl group or an aromatic group having alkyl groups in the 2,6-positions, such as mesityl, 2,6-diethylphenyl or 2,6-dimethylphenyl groups.
