| abstract |
The invention relates to novel dioxan derivatives of the formula R<SUP>1</SUP>-(A<SUP>1</SUP>-Z<SUP>1</SUP>)<SUB>m</SUB> - G- (Z<SUP>2</SUP>-A<SUP>2</SUP>)<SUB>n</SUB>-R<SUP>2</SUP>, in which G represents (I) or (II) and R<SUP>1</SUP>, R<SUP>2</SUP>, A<SUP>1</SUP>, A<SUP>2</SUP>, Z<SUP>1</SUP>, Z<SUP>2</SUP>, m and n are defined as cited in claim 1, to their use as a component or components in liquid crystal media and to liquid crystal and electrooptic display elements, which contain the novel liquid crystal media. |
