Synthesis of radio-metallofullerenols

We traced the synthesis process of water-soluble metallofullerenols using radioactivity. The synthesized yield of 153Sm@C82(OH)n from 153Sm@C82 was determined to be about 60%, but 26% of 153Sm were adsorbed in size-exclusion gel chromatography column. The recovery yields of activated Sm@C82(OH)n in nuclear reactor are 5–15% when using Sm@C82(OH)n as irradiation materials, and they are up to 65–88% when using Sm@C82(OH)n mixed with a quantity of C60(OH)m. It was found that the effective synthesis process for a radio-metallofullerenol is the neutron irradiation of metallofullerenol mixed with C60(OH)m.
