Abstract

New series of ferroelectric liquid crystals derived form alkoxycinnamic acid containing chiral alkyllactate group was synthesized. All compounds have a wide temperature range SmC* phase at temperatures above 100 degrees C and high spontaneous polarization. Some of homologues exhibit spontaneous helix twist unwinding in the SmC* phase accompanied with the helix twist inversion.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
