    摘要: The invention relates to chiral compounds of the general formula A--Y--(M--Y).sub.n --B--(Y--M).sub.n --Y--A where B is a radical of the formula ##STR1## and where the radicals A independently of one another are C.sub.1 - to C.sub.20 -alkyl which may be substituted by fluorine, chlorine, bromine or cyano and may be interrupted by O, S, NH, NCH.sub.3, COO or OCO, X are carbon or boron, Y independently of one another are a chemical bond, O, S, NH, N(CH.sub.3), 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.
