Abstract

Bicyclooctane derivatives of the formula I EQU R.sup.1 --A.sup.1 --A.sup.2 --R.sup.2 I wherein PA1 R.sup.1 and R.sup.2 independently of one another are each an alkyl group which has 1-12 C atoms and in which it is also possible for one or two non-adjacent CH.sub.2 groups to be replaced by O atoms and/or CO groups and/or --O13 CO groups and/or --CO--O groups and/or --CH.dbd.CH-- groups, one of the radicals R.sup.1 and R.sup.2 being also --A.sup.3 --R.sup.3, PA1 A.sup.1 is a 1,4-cyclohexylene group which is unsubstituted or substituted in the 1-position and/or 2-position and/or 3-position and/or 4-position by alkyl which has in each case 1-5 C atoms and is unsubstituted or substituted or fluorinated, and in which it is also possible for one or two non-adjacent CH.sub.2 groups to be replaced by one or two different groupings from the group --O--, --CO--, --CH.dbd.CH--, --S--, --SO-- or --SO.sub.2 --, or is substituted by F, Cl, Br, CN and/or CHO, PA1 A.sup.2 is a 1,4-bicyclo[2.2.2] octylene group, PA1 --A.sup.3 --R.sup.3 is --Cy--R.sup.3, --Ph--R.sup.3, --Cy--Ph--R.sup.3 or --Ph--Cy--R.sup.3, PA1 Cy is 1,4-cyclohexylene or one of the other groups recited for A.sup.1, PA1 Ph is 1,4-phe…
