Meta-substituted aromatic compounds having six-membered rings, for use in liquid-crystal mixtures Compounds of the formula I STR1 in which X is CH, CF or N, R2 is, for example, an alkyl, ether or ester group, which may also contain a chiral center, and R1 (--A1)a (--M1)b (--A2)c (--M2) d (--A3)e (--M3)f is a mesogenic radical, can advantageously be used as components of liquid-crystal mixtures, in particular ferroelectric liquid-crystal mixtures. The substances of the formula I have a particularly favorable effect on the optical switching angle and the critical pulse area of the mixtures.
