    • 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.
