New sorbents based on tetraphenylporphyrin bound to silica gel for the separation of C 60 and C 70 fullerenes

Sorbents prepared by reactions of chloromethyl- and chlorosulfo-derivatives of tetraphenylporphyrin (H 2TPP) with γ-aminopropyl-silica gel (γ-APS) exhibit good chromatographic characteristics in the separation of C 60 and C 70 fullerenes; the sorbent based on Al(X) tetraphenylporphyrin sorbed on hyd...

Zusammenfassung:Sorbents prepared by reactions of chloromethyl- and chlorosulfo-derivatives of tetraphenylporphyrin (H 2TPP) with γ-aminopropyl-silica gel (γ-APS) exhibit good chromatographic characteristics in the separation of C 60 and C 70 fullerenes; the sorbent based on Al(X) tetraphenylporphyrin sorbed on hydroxydimethylsilyl-silica gel [TPPAl(X)] is suitable for the large-scale separation of C 60 and C 70 fullerenes.
