  High Carrier Mobility up to 0.1 cm²/Vs and a Wide Mesomorphic Temperature Range of Alkynyl-Substituted Terthiophene and Quaterthiophene Derivatives

  摘要：

  Smectic semiconductors with high carrier mobility were designed and synthesized. The hole mobility of 3-TTP-yne-4 and 3-QTP-yne-3 at room temperature was 0.06 cm(2)/Vs and 0.1 cm(2)/Vs, respectively. They exhibit highly ordered smectic phases around room temperature, with softness to some extent, which make it possible homogeneous film with low defect density. Intermolecular distance in the smectic phase of 3-QTP-yne-4 is almost same as that of 3-TTP-yne-4. In this material, larger pi-conjugate system results in higher carrier mobility.

  日期：2006.11

  Liquid crystalline semiconductors have been recognized as one of promising materials potential for opto-electronics applications. However increase in carrier mobility as well as extension of mesomorphic temperature range is indispensable for practical applications, such as electroluminescence and thin film transistors. In this report, carrier transport in highly ordered smectic phases of oligothiophene derivatives is reported.
