High-Yield Synthesis of Endohedral Metallofullerenes Y@C_(2n) and Y_2@C_(2n)

摘要

A series of yttrium metallofullerenes some of them are first reported. have beensynthesized by the DC, are discharge method at high helium pressure. Mass spectra results showthat the contents of metallofullerenes are very’ high both in primary soot and in CS2 or DMF extract.and Y@C82, with ca 85% purity is obtained through column chromatographic isolation.
