Abstract
A process for separating C.sub.60, C.sub.70, and higher fullerenes above C.sub.70 is provided. The process employs a chromatographic column utilizing a functionalized aromatic-containing resin as the stationary phase, an organic solvent as the mobile phase, and a mixture of fullerenes dissolved in the mobile phase.
