Chiral smetic liquid crystals and glassy materials containing the same for displaying and storing information

摘要

The chiral smetic liquid-crystalline compounds of the general formula (I)PPM.sub.1.sup.* --B--M.sub.2.sup.* (I)P Psolidify on cooling from the liquid-crystalline phase in glassy form, as a result of which they are suitable for materials for displaying and storing information. Such materials may be used in electro-optic data stores or display components which are based on the ferroelectric or electroclinic switching effect in a chiral or chirally doped, smetic liquid-crystalline phase.PPIn the general formula, M.sub. 1.sup.*, M.sub.2.sup.* stand for chiral smetogenic groups and --B-- is, as bridging link, a typical bivalent group.
