Tris-Fused TTF Analogs Possessing Dendralene Moieties

Tris-Fused TTF Analogs Possessing [3]Dendralene Moieties 

CT complexes of 28b,c with TCNQ-F were successfully prepared. The ratio of the donor to TCNQ-F in the CT complexes is 1 1. The amounts of CT in the complexes were estimated to be 1.2 by comparison of the CN stretching shift. The electric conductivities of the compressed pellet of these CT complexes measured by the four-probe technique gave moderate electrical conductivities of o-jt = 3 X 10 S cm . Temperature dependence of their resistivity exhibited semiconducting properties, with activation energies of 0.10-0.13 eV.
