Abstract
The poor solubility of C60 and C70 in common organic solvents is now well established and it may lead to different problems in the daily work on fiillerenes. In the present work, we have investigated the temperature-dependent solubility of both C60 and C70 in tetralin, 1, 3-diphenylacetone and o-dichlorobenzene. In all cases, we observed a maximum of solubility in all solvents investigated. Although this maximum of solubility is not located at the same temperature for each solubility curve, the solubilities of C60 or C70 are of the same order of magnitude in these solvents. Thermodynamic parameters such as ΔH° and ΔS° have been determined and no correlation between these parameters and the solvent properties is shown.Keywords
