Solubility correlation of [60]fullerene in different solvents

The solubility of [60]fullerene in various solvents has been correlated to the molar volume ratio of [60]fullerene and the respective solvent. The sol ubility varies linearly with the molar volume for the alcohol series and th e heteroatom containing solvents, though specific interactions of the charg e transfer type seem to dominate in the case of aromatic hydrocarbons and t he halogenated solvents. The symmetric nature of the [60]fullerene and its clustering behavior could be the reason for the solubility variations obser ved in the solvents where specific interactions are present. The aggregatio n behavior of [60]fullerene molecule studied by laser light scattering tech nique in the solvent mixture of toluene and N,N-dimethyl formamide confirms the cluster formation and its dependence on the volume ratio in the binary solvent mixture.
