摘要：

The electron-accepting ability of a C60 molecule in solution was evaluated by the measurements of the charge transfer (CT) absorption energy and the redox potential. It was concluded that C60 is a weak electron acceptor comparable to 2,5-dibromo-p-xyloquinone, s-tetracyanobenzene or 2,3-dichloro-1,4-naphthoquinone. The adiabatic electron affinity of a C60 molecule was estimated as (2.10-2.21) +/- 0.1 eV. Several black solid CT complexes of C60 were prepared with mainly TTF derivatives and the ionicity of the ground state was examined by their CT band energies and vibrational spectra. These CT complexes were found to be neutral. A crystal structure of the OMTTF complex from benzene was determined.
