Results of ESR and conductivity measurements on undoped and iodine doped poly(tetrathiafulvalenes) are reported. The ESR properties of phenylene-bridged polymeric tetrathiafulvalenes which are substituted by CH3- or C2H5-groups and poly(tetrahydroanthratetrathiafulvalene) are described. The maximum spin concentration in the doped speciality polymers is about 1020 spins per gram. The conductivity of the variously doped samples lies in the area of 10−10 to 10−4 Scm−1 at room temperature and increases with temperature, as is typical for semiconductors.
