Multi-sulfur TTF derivatives with eight or nine sulfur atoms were synthesized for the development of new conducting organic salts. Their oxidation potentials were measured, and compared with those of the related donor molecules. The electrical conductivities of some of the ion radical salts were measured.
Bis(vinylenedithio)tetrathiafulvalene (BVDT-TTF) and bis(methylvinylenedithio)tetrathiafulvalene (BMVDT-TTF) were synthesized as attractive donor molecules for highly conductive organic salts. These molecules have analogous structures to BEDT-TTF, but are expected to possess more planar structures. They have higher oxidation potentials than BEDT-TTF. The synthetic method of BVDT-TTF by using a phase-transfer
The Synthesis of 4,5-Ethylenedithio-4′,5′-vinylenedithiotetrathiafulvalene (EVT) and Its Methyl and Dimethyl Derivatives (EMVT, EDMVT), and the Molecular and Crystal Structures of EVT
New donor molecules, 4,5-ethylenedithio-4′5′-vinylenedithiotetrathiafulvalene (EVT) and itsmethyl and dimethyl derivatives (EMVT and EDMVT), were synthesized for the study of conducting organic salts. They are unsymmetrical TTF derivatives possessing moieties of both BEDT-TTF and bis(vinylenedithio)tetrathiafulvalene (VT) or itsmethyl and dimethyl derivatives. Their oxidation potentials were measured
