(EN) PHENYL CYCLOHEXANES AND LIQUID CRISTAL MEDIUM
(FR) PHENYLCYCLOHEXANES ET MILIEU DE CRISTAUX LIQUIDES
Abstract:
(DE) Die Erfindung betrifft Phenylcyclohexane der Formel (I), worin Q (a), (b) oder (c), R Alkyl, Alkoxy, Oxaalkyl, Alkenyl oder Haloalkyl mit jeweils bis zu 12 C-Atomen, r 0 oder 1, X F, Cl, CF3, CHF2, OCF3 oder OCHF2, und L1, L2, Y und Z jeweils unabhängig voneinander H oder F bedeuten, mit der Maßgabe, daß im Falle Y = Z = H und gleichzeitig r = o und Q = (a), X CF3, CHF2, OCF3 oder OCHF2 und/oder L1 und/oder L2 F bedeutet.
(EN) The invention concerns phenyl cyclohexanes of formula (I) in which: Q is (a), (b) or (c); R is alkyl, alkoxy, oxaalkyl or haloalkyl, each with up to 12 C atoms; r is 0 or 1; X is F, Cl, CF3, OCF3 or OCHF2; and L1, L2, Y and Z are independently H or F, with the proviso that, if Y = Z = H and at the same time r = o and Q = (a), X is CF3, CHF2, OCF3 or OCHF2 and /or L1 and/or L2 is F.
(FR) L'invention concerne des phénylcyclohexanes de formule (I) où Q désigne (a), (b) ou (c), R désigne alkyle, alcoxy, oxaalkyle, alcényle ou haloalkyle avec chacun jusqu'à 12 atomes de C, r désigne 0 ou 1, X désigne F, Cl, CF3, CHF2 OCF3 ou OCHF2 et L1, L2, Y et Z désignent chacun indépendamment H ou F, à la condition que, lorsque Y = Z = H et que simultanément r = o et Q = (a), X désigne CF3, CHF2, OCF3 ou OCHF2 et/ou L1 et/ou L2 désignent F.
