Title (EN) LIQUID-CRYSTAL COMPOUNDS BEARING VINYL LINKAGES AND LIQUID-CRYSTAL COMPOSITION
(FR) COMPOSES DE CRISTAUX LIQUIDES COMPORTANT DES LIAISONS VINYLE ET COMPOSITION DE CRISTAUX LIQUIDES
Abstract:
(EN) Liquid-crystal compounds exhibiting a liquid-crystal phase over a wide temperature range and having a low viscosity, a high refractive anisotropy and a high elastic constant ratio (K33/K11); a liquid-crystal composition containing at least one of these compounds; and a liquid-crystal display element made by using this composition. The liquid-crystal compounds are represented by general formula (1), wherein R is C1-C10 alkyl or C2-C10 alkenyl; R'is C1-C10 alkyl, C2-C10 alkenyl, F, C1, CN, OCF3, CF3, OCF2H, CF2H or CFH2; and A1 and A2 are each independently trans-1,4-cyclohexylene, 1,4-phenylene wherein one or more of the hydrogen atoms on the 6-membered ring may be replaced by halogen, or a single bond, each of the elements constituting the compound being optionally replaced by an isotope thereof.
(FR) Cette invention concerne des composés de cristaux liquides qui restent en phase cristaux liquides sur une plage étendue de températures, et qui possèdent une faible viscosité, une anisotropie de réfraction élevée, ainsi qu'un rapport de constante élastique élevé (K33/K11). Cette invention concerne également une composition de cristaux liquides contenant au moins un de ces composés, ainsi qu'un élément d'affichage à cristaux liquides fabriqué à l'aide de cette composition. Les composés de cristaux liquides correspondent à la formule générale (1) où R représente alkyle C1-C10 ou alcényle C2-C10; R' représente alkyle C1-C10, alcényle C2-C10, F, Cl, CN, OCF3, CF3, OCF2H, CF2H ou CFH2; et A1 et A2 représentent chacun indépendamment trans-1,4-cyclohexylène ou 1,4-phénylène où un au moins des atomes d'hydrogène sur le noyau à 6 éléments peut être remplacé par halogène, ou une liaison unique, chacun des éléments constituant le composé pouvant être éventuellement remplacé par un de ses isotopes.
