✦ Synopsis

The electron-accepting ability of a C6o molecule in solution was evaluated by the measurements of the charge transfer (CT) absorption energy and the redox potential. It was concluded that C6o is a weak electron acceptor comparable to 2,5-dibromop-xyloquinone, s-tetracyanobenzene or 2,3-dichloro-l,4-naphthoquinone. The adiabatic electron affinity of a C6o molecule was estimated as (2.10-2.21)+0.1 eV. Several black solid CT complexes of C6o 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.
