Convenient separation of high-purity C60 from crude fullerene extract by selective complexation with AlCl3.
A purification procedure for C60 from the fullerene extract has been developed using the differential complexation of C60 and C70 with AlCl3 (or its conjugate acid) in CS2 solution. In addition to pure C60 (>99.8%), the procedure also provides C70-enriched fullerene mixture.
