(EN) PHENYLCYCLOHEXANES AND LIQUID CRYSTALLINE MEDIA
(FR) PHENYLCYCLOHEXANES ET MILIEU MESOMORPHE
Abstract:
(DE) Neue Phenylcyclohexane der Formel (I), worin Q Alkylen mit bis zu 5 C-Atomen oder eine Einfachbindung, A (a), (b), (c), (d), (e), (f), (g), -CH2CH2CH2CH2-, -CH2CH2- oder eine Einfachbindung, X F, Cl, -CF3, -CN, -OCF3, -OCHF2, Alkyl oder Alkoxy mit jeweils bis zu 7 C-Atomen, und Y und Z jeweils unabhängig voneinander H oder F bedeuten, mit der Maßgabe, daß im Falle X = CN und Y = Z = H A von der Einfachbindung verschieden ist, können als Komponenten flüssigkristalliner Medien verwendet werden.
(EN) New phenylcyclohexanes of formula (I), where Q stands for alkylene with up to 5 C atoms or a single bond, A stands for (a), (b), (c), (d), (e), (f), (g), -CH2CH2CH2CH2-, -CH2CH2- or a single bond, X stands for F, Cl, -CF3, -CN, -OCF3, -OCHF2, alkyl or alkoxy each of which has up to 7 C atoms, and Y and Z independently stand for H or F, provided that, if X = CN and Y = Z = H, A is different from the single bond, can be used as constituents of liquid crystalline media.
(FR) De nouveaux phénylcyclohexanes de formule (I) où Q est alkylène avec jusqu'à 5 atomes de carbone ou une liaison simple, A est (a), (b), (c), (d), (e), (f), (g), -CH2CH2CH2CH2-, -CH2CH2- ou une liaison simple, X représente F, Cl, -CF3, -CN, -OCF3, -OCHF2, alkyle ou alkoxy avec respectivement jusqu'à 7 atomes de C, et Y et Z représentent indépendamment H ou F, à condition que si X = CN et Y = Z = H, A soit différent de la liaison simple, peuvent être utilisés comme constituants de milieux mésomorphes.
