Convenient Separation of High-Purity C60 from Crude Fullerene Extract by Selective Complexation with AlCl_3
Abstract
A purification procedure for C60 from the fullerene extract has been developed using the differential complexation of C60 and C70 with AlCl_3 (or its conjugate acid) in CS_2 solution. In addition to pure C60 (>99.8%), the procedure also provides C70-enriched fullerene mixture.
