Carbocyclic compounds of the formula I ##STR1## wherein Q is a benzene or cyclohexane ring or a naphthalene system, X is in each case --CH.sub.2 --(CH.sub.2).sub.p -- where it is also possible for one or two non-adjacent CH.sub.2 groups to be replaced by --O--, --S--, --CO--, --O--CO--, --CO--O-- or --CH.dbd.CH--,

Carbocyclic compounds

Hexasubstituted cyclohexane compounds

Carbocyclic compounds of the formula I ##STR1## wherein Q is a benzene or cyclohexane ring or a naphthalene system,

Six-membered ring compounds of the formula I ##STR1## wherein A is a benzene or cyclohexane ring,

Carbocyclic six-membered ring compounds

Polymer compositions exhibiting liquid-crystalline phases contain chemically bonded mesogenic groups of the formula Ia and/or Ib: ##STR1## in which Q.sup.1 is H, alkyl or alkoxy having 1-5 C atoms, F, Cl, Br or CN,

Polymer compositions exhibiting liquid-crystalline phases

Triphenylene derivatives of the formula I ##STR1## wherein X.sup.1 to X.sup.6 are each, independently of one another, --SH, --SR, --SOR, --SO.sub.2 R or --S--COR, and each R is an alkyl group with up to 20 C atoms, it being possible for one or two CH.sub.2 groups to be replaced by O atoms and/or by unsubstituted or substituted vinylene or vinylidene groups, may be used as components of discotic liquid-crystalline phases.
