Influence of the electrolyte composition of the subphase on the structure of 2D films of fullerene C60

The morphology of 2D films of fullerene C₆₀ on interfaces has been studied by Brewster angle microscopy and atomic force microscopy. Fullerene C₆₀ tends to aggregate, forming supramolecular structures with a surface area per C₆₀ molecule from 21.6 to 2900 Ų. As the area per C₆₀ molecule decreases, monomolecular clusters gradually transform into multiplayer structures. The introduction of an electrolyte into the system prevents the formation of fullerene globules and favors the formation of more homogeneous films.
