摘要: Triphenylene derivatives of the formula I ##STR1## wherein X.sup.1 to X.sup.6 are each, independently of one another, --SH, --SR, --SOR, --SO.sub.2 R or --S--COR, and each R is an alkyl group with up to 20 C atoms, it being possible for one or two CH.sub.2 groups to be replaced by O atoms and/or by unsubstituted or substituted vinylene or vinylidene groups, may be used as components of discotic liquid-crystalline phases.
摘要翻译: 其中X 1至X 6各自独立地为-SH,-SR,-SOR,-SO 2 R或-S-COR的式I的三亚苯衍生物,并且每个R为至多20个的烷基 C原子,可以将一个或两个CH 2基团取代为O原子和/或被未取代或取代的亚乙烯基或亚乙烯基取代,可用作盘状液晶相的组分。
