Abstract: Optically active and mesogenic 1,3-dioxolane-4-carboxylic esters are suitable for use as dopants in liquid crystal mixtures. They lead to liquid-crystalline ferroelectric phases having short response times and to electroclinic phases having large electroclinic coefficients. Their particular advantage is that they induce a helix of very large pitch, so that there is no need for any helix compensation by other dopants. Moreover, the 1,3-dioxolane-4-carboxylic esters exhibit high UV stability.

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: Compounds which have a chiral, orthogonal, higher-order smectic phase, in particular a S B or a S E phase can be used in the region of this phase or phases as a display or switching medium in electro- optical display elements or switching elements which are based on the utilisation of the electrokinetic effect.

Abstract: Optically active esters of 1-acylproline of the general formula (I) in which at least one of the radicals R1 and R2 is a mesogenic radical, are suitable as dopes in ferroelectric liquid-crystal mixtures. Proline derivatives in which only the R1 radical is mesogenic are preferred.
