  • Oligothiophene derivatives have been wellknown as an p-type channel $material.^1$ Here, we report novel oligothiophene derivative containing alkylene linkage as an p-type channel material. Oligothiophene derivative containing alkylene linkage BE4TH was synthesized and characterized. BE4TH was prepared by a palladium-catalyzed crosscoupling reaction via zinc-substituted thiophene. B4TH and BH4TH exhibited high thermal stability and at least one transition temperature.

  • Oligothiophene derivatives have been well-known as an p-type channel material.$^1$ Here, we report novel oligothiophene derivative containing methylene linkage as an p-type channel material. Oligothiophene derivative containing methylene linkage BHTM was synthesized and characterized. BHTM was prepared by a palladium-catalyzed cross-coupling reaction via zinc-substituted thiophene. BHTM exhibited high thermal stability and at least one transition temperature.

  • New Oligothiophene derivatives having liquid crystalline property have been designed, synthesized and characterized. New oligothiophene derivatives were prepared by a palladium-catalyzed cross-coupling reaction via zinc-substituted thiophene. The structures of materials were characterized by various spectroscopies. The new obtained oligothiophene derivatives showed high thermal stability above 300 $^{\circ}C$ and exhibited several transition temperatures, evidence of mesophase. In field-effect transistors, a charge carrier mobility of 1.9 x $10^{-2}$ $cm^2$/Vs was observed.
