Crucial role of alkyl-substituted benzenes in the formation of intercalate derivatives of C-60
Intercalates of C-60 were obtained by a direct synthesis of C-60 Solution in xylene, ethylbenzene, n-propylbenzene, n-butylbenzene and terc-butylbenzene with methanol, ethanol and isopropanol, respectively -"guest". Alcohol-solvent system interacts with C-60 and forms binary and ternary isostructure intercalate products. Infrared spectra of all derivatives showed no change compared to the pure C-60. Binary intercalates are isostructural with the C-60 crystal structure the same as ternary intercalates synthesized from a saturated solution of C-60 in xylene, n-butylbenzene and terc-butylbenzene. Intercalates do not have stoichiometric relation alcohol : C-60. The presence of more voluminous solvents (terc-butylbenzene, xylene and n-butylbenzene) in ternary intercalates of C-60 affects the changes in intermolecular space of the C-60 crystal structure as well as the formation of new intermolecular interactions. In all cases of binary and ternary intercalated systems, alkyl-substituted benzene played the role of "donor" of the intercalating agent -"guest" in the C-60 crystal structures.
