Abstract

Nitrogen-containing heterocyclic compounds of the formula I EQU R.sup.1 --A.sup.1 --Z.sup.1 --A.sup.2 --[Z.sup.2 --A.sup.3 ].sub.n --R.sup.2 wherein PA1 R.sup.1 and R.sup.2 in each case independently of one another are an alkyl group with 1-15 C atoms, it also being possible for one or two non-adjacent CH.sub.2 groups to be replaced by O atoms and/or --CO-- groups and/or --O--CO-- groups and/or --CO--O-- groups, and one of the radicals R.sup.1 and R.sup.2 is also H, F, Cl, Br or CN, PA1 A.sup.1 is a 1,4-cyclohexylene group, it also being possible for one or two non-adjacent CH.sub.2 groups to be replaced by O atoms, a 1,4-bicyclo-(2,2,2)-octylene group or a 1,3-dithiane-2,5-diyl group, PA1 Z.sup.1 and Z.sup.2 in each case independently of one another are --CO--O--, --O--CO--, --CH.sub.2 CH.sub.2 --, --OCH.sub.2 --, --CH.sub.2 O-- or a single bond, PA1 A.sup.2 and A.sup.3 in each case independently of one another are a 1,4-phenylene group, pyrimidine-2,5-diyl group, 1,4-cyclohexylene group, it also being possible for one or two non-adjacent CH.sub.2 groups to be replaced by O atoms, 1,3-dithiane-2,5-diyl group or a 1,4-bicyclo(2,2,2)-octylene group and PA1 n is 0 or 1, with the prov…
