Title (EN) 1,3-DIOXANE DERIVATIVE AND LIQUID-CRYSTAL COMPOSITION CONTAINING THE SAME
(FR) DERIVE DE DIOXANNE-1,3 ET COMPOSITION DE CRISTAUX LIQUIDES LE CONTENANT
Abstract:
(EN) A 1,3-dioxane derivative represented by general formula (I), wherein R is a straight-chain alkyl group having 1 to 10 carbon atoms, A is a single bond or a -CH2CH2- group, n is 0 or 1 and the cyclohexane ring and the 1,3-dioxane ring are each in the trans configuration and having very high dielectric anisotropy and small birefringence and, particularly in the form of a liquid-crystal composition containing the same, being capable of providing a liquid crystal display drivable at a low voltage and having a wide visual angle when applied to a liquid crystal display.
(FR) Un dérivé de dioxanne-1,3 représenté par la formule générale (I), où R est un groupe alkyle en chaîne rectiligne possédant entre 1 et 10 atomes de carbone, A est une liaison simple ou un groupe -CH2CH2-, n est 0 ou 1, et le composé cyclique cyclohexane et le composé cyclique dioxanne-1,3 sont chacun dans la configuration trans, possède une anisotropie diélectrique très élevée et une biréfringence peu élevée et, notamment sous la forme d'une composition de cristaux liquides qui le contient, est capable de fournir un affichage à cristaux liquides qui peut fonctionner à basse tension et avoir un angle visuel large lorsqu'il sert à cette application.
