Crucial Role of Alkyl-Substituted Benzenes in the Formation of Intercalate Derivatives of C_(60)

摘要

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.
