Solubility of fullerene C60 and C70 in toluene, o-xylene and carbon disulfide at various temperatures

Abstract The solubilities of fullerene C60 and C70 in toluene, o-xylene and carbon disulfide between the melting point and boiling point of the solvents, respectively, have been measured. The temperature dependent solubility of C60 displays anomalous behaviors. A solubility maximum of C60 around 0 °C for toluene and carbon sulfide and around 30 °C for o-xylene was observed. The temperature-dependent solubility of C70 behaves normally for all the three solvents studied.
