| abstract |
The invention concerns mixtures of liquid-crystalline compounds containing at least two different substances of general formula (I) in which the radicals Z<1>, Z<2>, independently of one another, mean a polymerisable group, Y<1>, Y<2>, independently of one another, mean a direct bond, -O-, -COO-, -OCO- or -S-, A<1>, A<2>, independently of one another, mean a spacer, and R<1>, R<2> and R<3> mean conventional substituents. The invention further concerns novel compounds of the given formula, in which at least two of the radicals Z<1>, Z<2>, Y<1>, Y<2>, A<1> or A<2> do not correspond. The mixtures and compounds according to the invention are suitable, inter alia, as a base material for colouring effect and piezo materials, preferably in chirally doped form. |
