Abstract
Liquid crystal compounds of formula I may be used by themselves or they may be mixed with other liquid crystal compounds to give useful liquid crystal mixtures which may then be used in liquid crystal devices. The materials exhibit smectic mesophases and may therefore be used in ferroelectric, ferrielectric, antiferroelectric, themochromic and electroclinic devices. They may also be used as long pitch materials.
