Abstract
In this study, we designed a ferroelectric liquid crystalline semiconductor. A phenyterthiophene derivative having a double bond at the terminal of the side chain was synthesized using the Suzuki coupling reaction. This compound exhibits chiral smectic C and ordered smectic phases. In the chiral smectic phase, the spontaneous polarization reaches around 100 nC cm-2. Hole mobility in the phase is also determined to be 3 × 10-4 cm2 V-1 S-1 by a time-of-flight technique.
