Abstract
Eight different 1:1 charge-transfer complexes prepared from the three-dimensionally modified TCNQ's with TTF, TMTTF, and OMTTF can be classified into three groups, I-III, on the basis of the magnitude of both the degree of CT and the electrical resistivity.
These groups are characterized by small band gap semiconductivity with moderate CT, low conductivity with weak CT, and low conductivity with complete CT, respectively. The stacking mode of the complexes are also discussed.
