Abstract: The invention concerns polymerisable, liquid-crystalline compounds of general formula (I) in which the Z radicals, independently of one another, mean a polymerisable group having the structure CH2=CCl-, CH2=C(CH3)- or styryl; the Y radicals, independently of one another, mean a direct bond, -O-, -COO-, -OCO- or -S-; the A radicals, independently of one another, mean a spacer having 5 to 30 carbon atoms in which every third carbon atom can be replaced by 0, S, NH, N(CH3) or COO; R , R and R , independently of one another, mean conventional substituents. The compounds of the invention are suitable, inter alia, for preparing colouring agents ordered as cholesteric liquid crystals.

Abstract: The invention relates to chiral compounds containing at least one divalent or polyvalent chiral group, at least one polymerizable group, at least one spacer and at least one mesogenic group, and to their use as polymerizable, chiral dopes for the preparation of cholesteric networks. The novel compounds are suitable for use in electro-optical displays or as chiral dopes for nematic or cholesteric liquid crystals in order to produce layers which reflect in colors.

Abstract: The invention concerns mixtures of liquid-crystalline compounds containing at least two different substances of general formula (I) in which the radicals Z , Z , independently of one another, mean a polymerisable group, Y , Y , independently of one another, mean a direct bond, -O-, -COO-, -OCO- or -S-, A , A , independently of one another, mean a spacer, and R , R and R mean conventional substituents. The invention further concerns novel compounds of the given formula, in which at least two of the radicals Z , Z , Y , Y , A or A do not correspond. The mixtures and compounds according to the invention are suitable, inter alia, as a base material for colouring effect and piezo materials, preferably in chirally doped form.
