ABSTRACT:
Cyclohexylphenylpyrimidines of the formula (I) ##STR1## in which R.sup.1 is straight-chain or branched, chiral or achiral alkyl or alkenyl having 2 to 16 carbon atoms, in which one or two nonadjacent --CH.sub.2 -- groups may be replaced by --0--, --S--, --CO--, --COO--, --OCO--, --Si(CH.sub.3).sub.2 -- or --C(CH.sub.3).sub.2 --, and in which one or more hydrogen atoms of the alkyl or alkenyl radical may be replaced by fluorine atoms, and in which the terminal CH.sub.3 group of the alkyl may also be replaced by ##STR2## R.sup.2 is straight-chain or branched, chiral or achiral alkyl having 1 to 10 carbon atoms,
are particularly suitable components for ferroelectric liquid-crystal mixtures since they result in favorable properties, such as, for example, high contrast, when used in electrooptical switching and display devices.
