Abstract

Gd@C₈₂ and Gd₂@C₈₀ were selectively reduced and extracted from the raw soot in a high yield by using Al-Ni alloy in toluene/tetrahydrofuran (THF). By tuning the ratio of toluene and THF, Gd ₂@C₈₀ with purity higher than 95% was isolated directly from the raw soot without high performance liquid chromatography (HPLC) purification. Furthermore, we found that the anions of Gd@C₈₂ and Gd₂@C₈₀ could react with aqueous NaOH to form water-soluble Gd-metallofullerols, which are potential magnetic resonance imaging contrast agents.
