PREPARATIVE SEPARATION OF HIGHER FULLERENES BY HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY ON A TETRACHLOROPHTHALIMIDOPROPYL-MODIFIED SILICA COLUMN

The preparative chromatographic separation of buckminsterfullerene (C6 0) and the larger, related carbon spheres C70, C76, C2nu-and D3-C78 an d C84 on a tetrachlorophthalimidopropyl-modified silica stationary pha se was achieved and quantified. A 1-mg amount of a mixture of the high er fullerenes per injection can be separated on a 250 mm x 20 mm I.D. column using dichloromethane-hexane (33:67, v/v) as the mobile phase a nd 1,2-dichlorobenzene as the sample solvent.
