| Abstract: An improved, large amount and rapid separation/purification method for C60 was reported. The method is based on differential complexation of C60, C70 and higher fullerenes with AlCl3. The C70 and higher fullerenes complexed much stronger with AlCl3 and the resulting complexes precipitated out of the solution. The active carbon was added in the above solution to get rid of trace C70 and higher fullerenes remained in solution of CS2. In addition to pure C60 (99.8%),C70 enriched fullerenes mixture is gotten. The neutral fullerenes were identified by electrospray ionization mass spectrometry. | |
