摘要
Unusual solubility versus temperature dependence for C-60 fullerene in toluene and several other solvents is due to the formation of solid solvates. Temperature Maximum of Solubility (TMS) in toluene coincides with the incongruent melting point of the solvate with the mole ratio of C-60 to toluene 1 : 1.8 +/- 0.5. Similar results were obtained in the system C-60-bromobenzene, C-60-o-xylene, where solvates with the mole ratio 1 : 2 were found. Stoichiometry of the solvates of C-60 with the aromatic solvents are discussed in terms of incongruent melting.
