Abstract: Water-soluble polyhydroxylated fullerene derivatives(fullerenol) were synthesized,and their scavenging ability for ·OH-radical was studied by the combination of ESR spectroscopy and spin-trapping technique with phenyl-t-butyl-nitrone.It was found that fullerenols showed an excellent efficiency in eliminating ·OH free radicals generated by UV photolysis of H2O2.At an applied fullerenol concentration of 0.3mg/mL in the final solution,a radical scavenging efficiency of approximate 95% was achieved, revealing the potential use of these compounds as novel potent free radical scavengers in biological systems.

Key words: C60, Fullerenol, ·OH-radical, Spin-trapping, ESR
