    • 1-fluor-6,7-dihydro-5H-isoquinoline-8-one-derivatives of the formula (I) R (-M )a(-A -M )b(-A -M )c-B(-M -A )d(-M -A )e(-M )f-R , in which the symbols and indices have the following meanings: group B is (II); R , R are, for example, alkyl groups with 1-20 C atoms; M , M , M , M , M and M are, for example, -O-, -CO-O-, -O-CO- or a single bond; A , A , A and A are, for example, 1,4-phenylene, pyrimidine-2,5-diyl or trans-1,4-cyclohexylene; and a, b, c, d, e and f are 0 or 1, a condition being that the sum of b, c, d and e is 0, 1 or 2. Compounds of formula (I) in the pure state are colourless and as a rule form liquid crystalline mesophases in a temperature range favourable to electro-optical applications. The compounds are chemically and thermally stable and light stable.
