Nuclear Magnetic Resonance Spectra of Polyhydroxylated Fullerene [C.sub.60]

Polyhydroxylated fullerene [C.sub.60][(OH).sub.n] (with an estimated number of hydroxyl groups n = 38-44) synthesized from pure fullerene by mixing a benzene solution of [C.sub.60] with a NaOH aqueous solution in the presence of a catalyst was studied with [sup.1]H and [sup.13]C solid-state nuclear magnetic resonance. Possible features of the structure of a molecule shell were revealed from [sup.1]H NMR data. The [sup.13]C spectrum showed a peak splitting with an increase in temperature, which is probably due to fullerenol isomers.
