    Abstract: The invention relates to chiral 3,4-dihydro-2H-pyran compounds and diastereomers thereof, and to the use of these compounds as chiral dopants for liquid-crystalline systems. The invention furthermore relates to non-polymerizable or polymerizable liquid-crystalline compositions which comprise at least one chiral 3,4-dihydro-2H-pyran compound according to the invention, to the use of these non-polymerizable or polymerizable liquid-crystalline compositions for the production of optical components, to the use of the polymerizable liquid-crystalline compositions for printing or coating substrates, for the preparation or production of dispersions and emulsions, films or pigments and optical components of this type, printed or coated substrates, dispersions and emulsions, films and pigments.

    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: PCT No. PCT/EP95/00866 Sec. 371 Date Sep. 16, 1996 Sec. 102(e) Date Sep. 16, 1996 PCT Filed Mar. 9, 1995 PCT Pub. No. WO95/25150 PCT Pub. Date Sep. 21, 1995The invention relates to chiral compounds of the general formula A-Y-(M-Y)n-B-(Y-M)n-Y-Awhere B is a radical of the formula or and where the radicals A independently of one another are C1- to C20-alkyl which may be substituted by fluorine, chlorine, bromine or cyano and may be interrupted by O, S, NH, NCH3, COO or OCO, X are carbon or boron, Y independently of one another are a chemical bond, O, S, NH, N(CH3), COO or OCO and M independently of one another are a mesogenic group and n independently of one another are 0 or 1 with the proviso that one n is other than 0. The compounds according to the invention are suitable as dopes in liquid-crystalline media.
