(EN) 3,6-DISUBSTITUTED 2-HALOPYRIDINES
(FR) 2-PYRIDINES D'HALOGENES 3,6-DISUBSTITUEES
Abstract:
(DE) Die Erfindung betrifft Halogenpyridine der Formel (I), worin L Cl oder F bedeutet, und R1, R2, A1, A2, Z1, Z2, m und n die in Patentanspruch 1 gegebene Bedeutung besitzen und deren Verwendung als Komponenten flüssigkristalliner, insbesondere ferroelektrischer, Medien.
(EN) The invention concerns halopyridines of formula (I), in which L is Cl of F, and R1, R2, A1, A2, Z1, Z2, m and n are as defined in claim 1. The invention also concerns the use of these halopyridines as components of liquid-crystal, in particular ferro-electric, media.
(FR) La présente invention concerne des pyridines d'halogène de formule (I), où L représente Cl ou F, et R1, R2, A1, A2, Z1, Z2, m et n possèdent la notation indiquée dans la revendication 1, ainsi que leur utilisation comme composants de milieux cristallins liquides, en particulier ferroélectriques.
