Ferroelectric liquid-crystalline phenylterthiophene derivatives bearing a decenyl group, disiloxane chain, and cyclotetrasiloxane ring were synthesized. These compounds exhibited a chiral smectic C (SmC?) phase. The spontaneous polarizations of the compounds exceeded 50 nC cm-2. The hole mobilities determined by the time-of-flight method were in the order of 1 × 10-4 cm2 V-1 s-1. The compound with a decenyl group exhibited an anomalous photovoltaic effect in the SmC? phase although the conversion efficiency was lower than 0.01%. Notably, even the compound bearing a bulky cyclotetrasiloxane ring exhibited an enantiotropic SmC? phase.
