摘要

Phase transitions, smectic layer structure, helical pitch and electrooptical properties of recently prepared high tilted antiferroelectric compounds are characterized. The compounds enable to prepare broad temperature range (−20 to 100 °C) orthoconic antiferroelectric mixtures, having 45° tilt independent of temperature in broad temperature range, and exhibiting excellent contrast and grey level scale.
