Title (EN) HALOPHENYL SUBSTITUTED HETEROCYCLIC DERIVATIVES
(FR) DERIVES HETEROCYCLIQUES SUBSTITUES PAR HALOPHENYLE
Abstract:
(EN) The invention relates to halophenyl substituted heterocyclic derivatives of formula (I) wherein R1, -A1-, -A2-, Z, L1, Hal, m and o have the meaning given in Claim 1, and to their use as components of liquid crystalline media for electro-optical displays.
(FR) Des dérivés hétérocycliques substitués par halophényle et répondant à la formule (I), dans laquelle R1, -A1-, -A2-, Z, L1, Hal, m et o ont la même signification que celle présentée dans la revendication numéro 1. Lesdits dérivés peuvent servir d'élément de milieux à cristaux liquides destinés aux affichages électro-optiques.
