摘要：
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.
