Fluorine-containing, chiral liquid crystal compounds comprise (a) a chiral fluorochemical terminal portion containing at least one methylene group and optionally containing at least one catenary ether oxygen atom; (b) a saturated, chiral or achiral, 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.
含氟手性液晶化合物包括:(a)含有至少一个亚甲基基团且可选地含有至少一个链醚氧原子的手性氟化学末端部分;(b)饱和的手性或非手性烃基末端部分;以及(c)连接末端部分的中心核。这些化合物具有液晶相或潜在的液晶相,并且例如在液晶显示器件中有用。
