Popis: Structural and dimensional features of C 60 aggregates in toluene solution prepared in two different ways – equilibrium and strongly non-equilibrium – were studied by high-resolution transmission electron microscopy and atomic-force microscopy methods. It was found that in solutions prepared by the non-equilibrium method (stirring of solution of C 60 by a mechanical rotator), large quasispherical aggregates (with a diameter of up to ∼ 380 ± 20 nm ) of nanoporous structure with fractal size D ≈ 2.13 were synthesized. In the case of solutions C 60 , which were prepared by the equilibrium method (without the use of external mechanical influences on solution), the formation of densely packed monomolecular fullerene aggregates with a diameter of not more than 50 nm was observed.
