Abstract:

The solubilities of C60 and C70 in toluene, o-xylene and CS2 between melting point and boiling point have been measured. The temperature-dependent solubillty of C60 displays the anomalous behavior. A solubility maximum of C60 around O℃ for toluene and CS2, and around 30℃ for o-xylene was observed. The temperature-dependent solubility of C70 displays the normal behavior in the same solvents.

Key words: Fullerene, C60, C70, Solubility
