Abstract

Self-assembling features of molecules of C₇₀ in benzene solution prepared in two various ways – equilibrium and non-equilibrium – has been investigated experimentally by method of high-resolution transmission electron microscopy. It was demonstrated, that the formation of densely packed monomolecular fullerene aggregates with a diameter of not more than 30 nm in solutions prepared by the equilibrium method (without the use of external mechanical influences on solution). In the case of solutions C₇₀, which were prepared by the non-equilibrium method (stirring of solution of C₇₀ by a mechanical rotator), large quasispherical aggregates of nanoporous structure with fractal size D ≈ 2.19 were synthesized.
