Thienoquinonoid-extended analogues of bis(alkylenedithio)tetrathiafulvalenes and their conductive complexes
Abstract
Three thienoquinonoid-extended analogues of bis(alkylenedithio)tetrathiafulvalenes, which are symmetric and unsymmetric conjugation-elongated donors, are synthesized and TCNQ complexes of these donors are proved to exhibit a metallic temperature dependence or a fairly high room temperature conductivity even when measured on compressed powder samples.
