Document Type and Number:
Japanese Patent JPS61227546
Kind Code:
A
Abstract:
Carbocyclic compounds of the formula I &cir& Q [X(A1Z)nA2R]m I- wherein Q is a benzene or cyclohexane ring or a naphthalene system, X is in each case -CH2-(CH2)p- wherein it is also possible for one or two non-adjacent CH2 groups to be replaced by -O-, -S-, -CO-, -O-CO-, -CO-O- or -CH=CH-, p is 0, 1 or 2, A1 and A2 independently of one another are each a 1,4-phenylene group which is unsubstituted or monosubstituted or polysubstituted by halogen atoms and/or CH3 groups and/or CN groups and in which it would also be possible for one or more CH groups to be replaced by N atoms, a 1,4-cyclohexylene group wherein it would also be possible for one or two non-adjacent CH2 groups to be replaced by -O- and/or -S-, a piperidine-1,4-diyl group or a 1,4-bicyclo[2.2.2]octylene group, Z is -CO-O-, -O-CO-, -O-, -CH2-, -CH2O-, -OCH2-, -CH2CH2-, -CHCN-CH2-, -CH2-CHCN-, -CH=CH-, -CH=N-, -N=CH-, -NO=N-, -N=NO- or a single bond, n is 0, 1 or 2 and R is alkyl having 1 to 20 C atoms wherein it would also be possible for one or more non-adjacent CH2 groups to be replaced by -O-, -CO-, -O-CO-, -CO-O- or -CH=CH-, H, F, Cl, Br, I, OH, NH2, COOH or CN, m being 6 in the event that Q=benzene or cyclohexane and being 8 in the event that Q=naphthalene, subject to the proviso that, in the event that X=-OCH2- and -(A1-Z)n-A2-R=p-alkoxyphenyl, Q is a cyclohexane ring, are suitable for use as components of discotic, liquid-crystal phases.
