investigation, including the growth of single crystal films, polar deposition of Langmuir-Blodgett multilayers, electrically poled polymer films, and self-assembled multilayers. In this communication, we describe a new approach for achieving designed organic thin films with thermodynamically stable, polar orientation of functional groups using ferroelectricliquidcrystal polymers (FLCPs).

(EN) 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.(FR) La présente invention concerne des composés chiraux pour cristaux liquides, contenant du fluor. Ces composés comprennent (a) une terminaison fluorocarbone aliphatique comportant au moins deux atomes en chaîne d'oxygène de l'éther; (b) une terminaison chirale hydrocarbonée aliphatique; et (c) un noyau central reliant les terminaisons. Ces composés comportent des mésophases smectiques ou des mésophases smectiques à l'état latent et conviennent notamment aux dispositifs d'affichage à cristaux liquides.
