Abstract: Sorbents prepared by reactions of chloromethyl- and chlorosulfo-derivatives of tetraphenylporphyrin (H₂TPP) with γ-aminopropyl-silica gel (γ-APS) exhibit good chromatographic characteristics in the separation of C₆₀ and C₇₀ fullerenes; the sorbent based on Al(X) tetraphenylporphyrin sorbed on hydroxydimethylsilyl-silica gel [TPPAl(X)] is suitable for the large-scale separation of C₆₀ and C₇₀ fullerenes.
