Dissolution and solubility. (A) Formation of clusters of fullerene with organic solvents, for the final structures clusters full view (left side) and its cross section (right side) are shown, organic solvent covers fullerene from outside and are present in small quantities inside the cluster, reproduced from Lehto et al.
