Fullerenes in molecular liquids. Solutions in “good” solvents: Another view

► The fullerene hydrosols exhibit all features of hydrophobic dispersions. ► In polar organic solvents, the fullerenes form typical organosols. ► Solvophobic solvation of fullerene molecules takes place even in “good” solvents. ► The C60 and C70 molecules can be considered as colloidal (or sub-colloidal) species, inclined to aggregate formation. ► The solvophobic effect and the van-der-Waals attraction are driving forces of permanent (though sometimes very slow) aggregate formation.
