Abstract
Separation of C-60 and C-70 fullerenes by HPLC was studied using sorbe nts synthesized by reaction of perylenedicarboxylic anhydride, dimetho xyviolanthrene, the tetramer of chromotropic acid with formaldehyde (T CA), trinitrobenzoyl chloride, or chlorotrinitrobenzene with gamma-ami nopropyl silica. These sorbents possess satisfactory chromatographic p roperties. The sorbent based on TCA is effective for separation of pre parative amounts of fullerenes.
