The equilibrium constant for complexation of C-60 and aniline in toluene has been determined by UV/wis spectroscopy, with a value of K = 0.28 +/- 0.04 obtained. The first extracted and well-defined charge-transfer (CT) bands have been observed for complexes of Csa with a variety of aromatic amines, with CT band maxima moving to higher frequency with increasing amine ionization potential. FTIR spectra of solid C-60 With substituted anilines show slight blue shifts in C-60 bands, indicative of a small amount of donor-acceptor interaction.
