Synthesis and Characterization of Liquid Crystalline Semiconducting Materials, Dialkyl-2-phenylnaphthalene Derivatives—Mesomorphic behavior and Charge carrier transport
摘要:
For establishment of high electronic charge carrier transport at ambient temperature, dialkyl derivatives of 2-phenylnaphthalene have been synthesized and characterized their liquid crystalline behaviors and photoelectrical properties. These materials exhibited smectic mesophases (Smectic A, B and E phases), at fairly low temperature range extended down below ambient temperature. Fast electronic transport of positive carriers was observed in SmE phase of 2-(4'-octylphenyl)-6-butylnaphthalene at 30degreesC, whose mobility was over 10(-2) cm(2)/Vs.
