Piezoelectric and Electric‐Field‐Induced Properties of a Ferroelectric Bent‐Core Liquid Crystal

A new adamantane bent-core liquid crystal exhibiting a metastable ferroelectric phase with large polarization is synthesized and characterized. The material shows reversible switching between a birefringent (opaque) and an optically isotropic (clear) state. In the clear state, the observed piezoelectric constant is comparable to those of commercial solid-state piezotransducers.
