Abstract

Nitrogen-containing heterocyclic compounds of the formula I EQU R.sup.I --(A--Z).sub.n --A--R.sup.2 I PA0 wherein R.sup.1 and R.sup.2 in each case independently of one another are alkyl group with 1-15 C atoms, wherein one or two non-adjacent CH.sub.2 groups can also be replaced by 0 atoms and/or --CO-- group and/or --O--CO-- groups and/or --CO--O-- groups, and one of the radicals R.sup.1 and R.sup.2 can also be H, CN, F, Cl or Br, the groups A in each case independently of one another are a 1,4-phenylene group, wherein one or two CH groups can also be replaced by N atoms, a 1,4-cyclohexylene group, wherein one or two CH.sub.2 groups which are not adjacent can be replaced by 0 atoms, a 1,3-dithiane-2,5-diyl group, a 1,4-bicyclo(2,2,2)-octylene group, a decahydronapthalene-2,6-diyl group or a 1,2,3,4-tetrahydronaphthalene-2,6-diyl group, the group Z 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 and n is 3 or 4, with the proviso that (a) at least one of the groups A is a "1,4" phenylene group, wherein two CH groups are replaced by N atoms, and (b) at least one of the other groups A contains …
