摘要：
Fluorine-containing, chiral liquid crystal compounds comprise (a) an aliphatic fluorocarbon terminal portion containing at least two catenary ether oxygen atoms; (b) a chiral, aliphatic hydrocarbon terminal portion; and (c) a central core connecting the terminal portions. The compounds have smectic mesophases or latent smectic mesophases and are useful, for example, in liquid crystal display devices.
