ABSTRACT:
The present invention relates to alkyne compounds of the formula Iin-line-formulae description="In-line Formulae" end="lead"?P1—Y1-A1-Y3-(T1-B1-)m-T3-C≡C-T4-(B2-T2-)n-Y4-A2-Y2—P2  (I)in-line-formulae description="In-line Formulae" end="tail"?in whichP1, P2are each, independently of one another, hydrogen, C1-C12-alkyl, a polymerizable group or a group suitable for polymerization or a radical which carries a polymerizable group or a group suitable for polymerization,Y1, Y2, Y3, Y4are each, independently of one another, a linking unit,B1, B2are each, independently of one another, —C≡C— or a linking group as defined for Y1to Y4,A1, A2are each, independently of one another, a single chemical bond or a spacer having from one to 30 carbon atoms,T1, T2, T3, T4are each, independently of one another, a divalent saturated or unsaturated carbocyclic or heterocyclic radical, andm, n are each, independently of one another, 0 or 1,with the proviso that at least one of the linking units Y3or Y4is a group —O—CO—O—, —O—CO—N(R)—, —(R)N—CO—O— or —(R)N—CO—N(R)—.The invention further relates to nonpolymerizable and polymerizable liquid-crystalline compositions comprising at least one alkyne compound of the formula I according to the invention, the use of these nonpolymerizable and polymerizable liquid-crystalline compositions for producing optical components, the use of the polymerizable liquid-crystalline compositions for printing or coating substrates, for preparing dispersions and emulsions, for producing films and pigments and optical components, printed or coated substrates, dispersions and emulsions, films and pigments of this type.
