Membraning and Conductivity of Polymeric Bis-ethylenedithio-tetrathiafulvalenes

Two kinds of polymeric BEDT TTFs were synthesized by polycondensation of bis hydroxy methyl or bis methyl formylate substituted bis ethylenedithio tetrathiafulvalenes with adipic chloride or hexandiol,respectively.Their molecular weights were measured by GPC.Effects of polymerization on membraning of the polymers were discussed.After oxidation,the CT complexes of the polymers with iodine were obtained and their conductivities and conducting stability were measured.
