The equilibrium constants for complexation of C 60 with naphthalene, phenanthrene and pyrene in toluene have been determined by UV/visible spectroscopy. The magnitude of the equilibrium constants was found to increase with decreasing ionization potential of the donor. Values for complexation enthalpy have been determined for the first time for C 60/aromatic hydrocarbons. Well-defined charge transfer (C-T) bands have been observed for complexes of C 60 with a variety of aromatic hydrocarbons, with C-T band maxima moving to higher frequency with increasing donor ionization potential.
