1. A liquid-crystalline medium, comprising
a polymerizable component (A) containing one more polymerizable compoundsand
a liquid-crystalline component (B) containing one more compounds of formula Iin whichR0 is an alkyl or alkenyl radical having from 1 to 15 carbon atoms which is unsubstituted, monosubstituted by CN or CF3 or at least monosubstituted by halogen, in which one or more CH2 groups are optionally, independently of one another, replaced by —O—, —S—,—CO—, —CO—O—, —O—CO—, —O—CO—O—, —CH═CH— or —C≡C— in such a way that O atoms are not linked directly to one another,are each independentlyY1 and Y2 are each, independently of one another, H or F,Z1 is —CF2O—, —OCF2— or —COO—,Z2 is —O—, —S—, —CO—, —COO—, —OCO—, —S—CO—, —CO—S—, —OCH2—, —CH2O—, —SCH2—, —CH2S—, —CF2O—, —OCF2—, —CF2S—, —SCF2—, —CH2CH2—, —CF2CH2—, —CH2CF2—, —CF2CF2—, —CH═CH—, —CF═CH—, —CH═CF—, —CF═CF—, —C≡C— or a single bond,X0 is F, Cl, halogenated alkyl, halogenated alkenyl, halogenated alkoxy, or halogenated alkenyloxy having up to 6 carbon atoms, andr is 0, 1, 2 or 3,and wherein the liquid-crystalline medium comprises one or more compounds of formulae XXIV-1 to XXIV-4in which R0 has the meaning given for said group in the compound of formula I. |
