The invention relates to chiral 1,3-dioxane compounds and their diastereomers of the general formula I. in which R 1 , R 2 and R 3 have the meaning given in the description, and the use of these compounds as chiral dopants for liquid-crystalline systems.n n n The invention further relates to non-polymerizable or polymerizablenliquid crystalline compositions, which at leastna chiral 1,3-dioxane compound of the formulan(I) contain the use of this non-polymerizablenor polymerizable liquid crystalline compositions fornthe production of optical components, the use of the polymerizablenliquid crystalline compositions for printingnor coating of substrates for the production of dispersionsnand emulsions, films or pigments as well as such optical components,nprinted or coated substrates, dispersions andnEmulsions, films and pigments. |
