Carbocyclic compounds

Carbocyclic compounds of the formula I in which Q is a benzene or cyclohexane ring or a naphthalene system, X radicals are in each case in which one or two non-adjacent CH2 groups can also be replaced by -O-, -S-, -CO-, -O-CO-, -CO-O- or -CH=CH-, p denotes 0, 1 or 2, A and A independently of one ano...

Summary:Carbocyclic compounds of the formula I in which Q is a benzene or cyclohexane ring or a naphthalene system, X radicals are in each case in which one or two non-adjacent CH2 groups can also be replaced by -O-, -S-, -CO-, -O-CO-, -CO-O- or -CH=CH-, p denotes 0, 1 or 2, A and A independently of one another in each case denote a 1,4-phenylene group which is unsubstituted or mono- or polysubstituted by halogen atoms and/or CH3 groups and/or CN groups, and in which one or more CH groups can also be replaced by N atoms, or denote a 1,4-cyclohexylene group in which one or two non-adjacent CH2 groups can also be replaced by -O- and/or -S-, or denote a piperidine-1,4-diyl group or 1,4-bicyclo[2.2.2]octylene group, Z denotes -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 denotes 0, 1 or 2 and R denotes alkyl having 1 to 20 C atoms in which one or more non-adjacent CH2 groups can also be replaced by -O-, -CO-, -O-CO-, -CO-O- or -CH=CH-, or denotes H, F, Cl, Br, I, OH, NH2, COOH or CN, where m is 6 if Q is benzene or cyclohexane and 8 if Q is naphthalene, with the proviso that, in the event that X is -OCH2- and is p-alkoxyphenyl, Q is a cyclohexane ring, are suitable as components in discotic liquid-crystalline phases.
