摘要
In order to isolate and purify an endohedral fullerene, a solvent washing was performed using toluene to concentrate the endohedral fullerene in a residual, but endohedral fullerene could not be efficiently purified because impurities other than the endohedral fullerene could not be sufficiently removed. Thus, the endohedral fullerene is isolated and purified by using a solvent such as chloronaphthalene or tetralin having a high solubility for the endohedral fullerene and concentrating the endohedral fullerene in the solvent. The endohedral fullerene isolated and purified by solvent extraction has a cluster structure where the endohedral fullerene is surrounded with empty fullerenes. Thus, this endohedral fullerene is highly stable and is a useful material applicable to various fields such as medical care and electronics.
