Claim 0:
1. A liquid-crystalline medium, comprising one or more compounds of formula IA, in which
R11 and R12 identically or differently, denote H, an alkyl or alkoxy radical having 1 to 15 C atoms, in which one or more CH2 groups in these radicals are optionally replaced, independently of one another, by —C≡C—, —CF2O—, —OCF2—, —CH═CH—,, —CO—O— or —O—CO— in such a way that O atoms are not linked directly to one another, and in which one or more H atoms may be replaced by halogen,
