摘要
A new and efficient extraction method using DMF (N,N-dimethylformamide) was developed to concentrate endohedral metallofullerenes. This single-step extraction method obtained a solution containing 5-15% endohedral metallofullerenes and strongly discriminated against the dominant C-60, C-70, and higher empty fullerenes in raw soot. This highly selective extraction procedure substantially reduced sample loading in the HPLC isolation for a given volume of sample injection. The efficiency of our separation method is demonstrated by the isolation of the endohedral metallofullerene Ce@C-82.
