Nuclear Magnetic Resonance Spectra of Polyhydroxylated Fullerene C 60 (OH) n

Polyhydroxylated fullerene C60(OH)n (with an estimated number of hydroxyl groups n = 38–44) synthesized from pure fullerene by mixing a benzene solution of C60 with a NaOH aqueous solution in the presence of a catalyst was studied with 1H and 13C solid-state nuclear magnetic resonance. Possible features of the structure of a molecule shell were revealed from 1H NMR data. The 13C spectrum showed a peak splitting with an increase in temperature, which is probably due to fullerenol isomers.
