Abstract: Aseries of high efficient stationary phases of HPLC, FUL-1, FUL-2, FUL-3 and FUL-4, with different separation function groups for the separation of C60and C70were prepared on the basis of analysis of relationship between intermolecular forces and molecular structures.FUL-1, FUL-2 and FUL-3 can be successfully used to separate C60and C70from each other with benzene, toluene and o-xylene as mobile phase, respectively.The action force between FUL-4 and C60or C70is so strong that no solution has been found to elute C60or C70from FUL-4 column, Of all these stationary phases, FUL-3 is the best because of the highest solubilities of Fullerenes in o-xylene and the highest separation factors of Fullerenes in this system.

Key words: Separation of C60and C70, Stationary phase, HPLC
