    Abstract: Chiral glucosides of the type 2,4,7-trioxa-bicyclo(4.4.0)decane compounds are new. Chiral glucosides of the type 2,4,7-trioxa-bicyclo(4.4.0)decane compounds of formula (I) are new (when R = R = H). An Independent claim is also included for cholesteric liquid crystal compositions comprising a wider range of compounds of formula (I) (when R = R = as below), optionally in admixture with achiral liquid crystal polymerizable monomers of formula (II). R = Z -Y -(A )m-Y -M -Y -(A )n-Y -; R = H, 1-12C alkyl, 1-12C alkylcarbonyl, aryl, arylcarbonyl or Z -Y -(A )o-Y -M -Y -(A )p-Y -; R = H, 1-12C alkyl, aryl or OR ; R = H, 1-12C alkyl, aryl or OR ; R , R = H, 1-12C alkyl, 1-12C alkylcarbonyl, aryl, arylcarbonyl or Z -Y -(A )q-Y -M -Y -(A )r-Y -; A -A = 1-30C spacer group; M -M = mesogenic group; Y -Y and Y -Y = bond, -O-, -S-, -C(=O)-, -C(=O)-O-, -O-C(=O)-, -CH=CH-C(=O)-O-, -O-C(=O)-O-, -C(=O)-N(R)-, -(R)N-C(=O)-, -CH2-O-, -O-CH2-, -CH=N-, -N=CH- or -N=N-; Y , Y = bond, -C(=O)-, -O-C(=O)-, -CH=CH-C(=O)-, -(R)N-C(=O)-, -CH2- or -O-CH2-; R = H or 1-4C alkyl; Z -Z = H, 1-12C alkyl, polymerizable group or a residue containing a polymerizable group; and m-t = 0 or 1.

    Abstract: The invention concerns compounds containing chiral groups of general formula (I) in which B is a single or double bond and R is C1-C30 alkyl optionally substituted by fluorine, chlorine, bromine, cyanogen or hydroxy and optionally interrupted by O, S, NH, N(CH3), COO or OCO, phenyl optionally substituted by fluorine, chlorine, bromine, cyanogen, C1-C20 alkyl, C1-C20 alkoxy or C1-C20 alkoxycarbonyl, or C5-C7 cycloalkyl or fluorine, chlorine, bromine or cyanogen, the free valence being linked to a carbon atom. The compounds according to the invention are suitable for use in liquid-crystal media in display technology, in optical, electronic and opto-electronic storage media, electronic data processing and reproduction or electrophotography and in light-reflecting layers.

    Abstract: The invention relates to compounds of general formula (I) in which the radicals: X is mutually independently boron; CH2 or (a), B is hydrogen, C1 to C8 alkyl, phenyl, biphenylyl or a radical of formula (II); A and A are spacers; n is 0, 1, 2 or 3; m is 1 of zero for X = CH2; M and M are possibly fluorine-, chlorine-, bromine-, cyano-, hydroxy- or nitro-substituted single or multi-nuclear aliphatic, aromatic, heteroaliphatic or heteroaromatic ring systems, the radicals Y are mutually independently a direct bond O, S, COO, OCO, OCOO, CON(R) or N(R)CO; Z and Z are polymerisable groups or hydrogen; R is hydrogen or C1 to C4 alkyl and R and R are hydrogen; possibly O, COO, OCO, OCOO or N(R)-interrupted C1 to C30 alkyl, C2 to C30 alkenyl, C1 to C30 alkanoyl or C3 to C30 alkenoyl or a radical of formula (III) where T is a direct compound, CO, CH2, CH=CH-CO, CH2CH2CO or SO2 and A, M, Y, Z, n and m have the meanings given. The compounds of the invention are suitable as e.g. chiral doping agents for electro-optical display components or for nematic or cholesteric liquid crystals for the generation of coloured reflecting coatings of the production of liquid crystalline cholesterically ordered pigments.

    Abstract: The invention concerns compounds of general formula (I) Z-Y-A-(Y-M)n-Y -X-Y -(M-Y)n-A-Y-Z in which the groups A, independently of one another, are spacers, n is 1, 2 or 3, X is a group of formula (a), (b), (c), (d), (e), (f), (g) or (h), the groups Y , independently of one another, designate O, OCO, OCOO, or a direct bond, the groups Y, independently of one another, designate O, S, CO, COO, OCO, OCOO, CONR, NRCO or a direct bond, R is hydrogen or a C1-C4 alkyl, the groups M, independently of one another, designate an aliphatic, aromatic, heteroaliphatic or heteroaromatic ring system optionally substituted by chlorine, bromine, fluorine, iodine, cyan or methyl, and the groups Z, independently of one another, designate hydrogen or a polymerizable group. These compounds are suitable for use in electro-optical display elements, as chiral doping substances for nematic or cholesteric liquid crystals for producing coloured reflective layers or pigments disposed cholesterically by liquid crystals.
