SOLUTION AND SOLID-STATE INTERACTIONS OF C-60 WITH SUBSTITUTED ANILINES

The equilibrium constant for complexation of C-60 and aniline in tolue ne has been determined by UV/wis spectroscopy, with a value of K = 0.2 8 +/- 0.04 obtained. The first extracted and well-defined charge-trans fer (CT) bands have been observed for complexes of Csa with a variety of aromatic amines, with CT band maxima moving to higher frequency wit h increasing amine ionization potential. FTIR spectra of solid C-60 Wi th substituted anilines show slight blue shifts in C-60 bands, indicat ive of a small amount of donor-acceptor interaction.
