We have found a novel organic semiconductor, BTQBT, with a high electrical conductivity of about 10^{-3} S cm^{-1} and a high Hall mobility of about 3 cm^{2} V^{-1}s^{-1} at room temperature. We have also succeeded in mea­suring the temperature dependence of the Hall mobility. It varies with tem­perature as Τ^{-1.6}, which agrees with the theoretical Τ^{-1.5} dependence for the mobility determined by lattice scattering. The characteristic transport property of BTQBT results from strong intermolecular interactions in the crystal, which is convinced by the energy dispersion with a bandwidth of about 0.5 eV from the theoretical and experimental band structures.
