    Abstract: The novel compounds are aryl-2,3-epoxyalkyl ethers or thioethers or the corresponding thiirane compounds having a mesogenic aromatic component and a chiral component having a three-membered heterocyclic ring, wherein, in the general formula (1), (I) the symbols have the following meaning: R1=straight-chain or branched (C1-C12) alkyl, where one or two non-neighboring CH2 groups may be replaced by O or S atoms. A=diazine-2,5-diyl or diazine-3,6-diyl, X and Y=O and/or S, and R2, R3 and R4, independently of one another=H, straight-chain (C1-C10) alkyl or branched (C3-C10) alkyl, where R2, R3 and R4 are not simultaneously H. The compounds are preferably employed in tilted smectic liquid-crystal phases which they convert into ferroelectric liquid-crystal phases; they have high values for spontaneous polarization or they induce high values for spontaneous polarization.

    Abstract: Cyclohexylphenylpyrimidines of the formula (I) anched, chiral or achiral alkyl or alkenyl having 2 to 16 carbon atoms, in which one or two nonadjacent -CH2- groups may be replaced by -0-, -S-, -CO-, -COO-, -OCO-, -Si(CH3)2- or -C(CH3)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 CH3 group of the alkyl may also be replaced by R2 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.
