Several CT complexes of HMTTeF with TCNQs, quinones, and other acceptors were prepared and electrical and optical properties were examined. A linear correlation between the resistivities and the position of CT bands was observed. In general, 1:1 complexes with strong acceptors(EAA > 2.60eV) show relatively high conductivity with low activation energy as well as strong electronic absorption extending to IR region. Single crystals of TCNQ and 2,5-dimethyITCNQ complexes show metallic character, in which Peierls transition is strongly suppressed.
