Abstract
Several derivatives of 2,2'-ethanediylidenebis(1,3-dithiole) fused with 1,3
-dithiol-2-ylidenes (DT-EBDTs) have been prepared. Their cyclic voltammogra
ms consist of three single-electron redox waves. The first redox potential
of MeDT-EBDT (+0.37 V vs. SCE in PhCN) is lower by 0.08 V than those of the
corresponding TTF, MeDT-TTF. On the other hand, the E-2-E-1 value (0.13 V)
is smaller by 0.18 V than that of MeDT-TTF. The present donors afford semi
conducting AsF6- salts, TCNQF(4) and DDQ complexes (sigma(rt) = 10(-5)=10(-
1) S cm(-1), E-a, = 0.03-0.19 eV).
