Vorgeschlagen werden neue flüssigkristalline Derivate von stickstoffhaltigen heterocyclischen Systemen der allgemeinen Formel R¹-A¹-Z-A²-R² (1) worin R¹ und R² gleichzeitig oder unabhängig CnH2n+1, -CmH2m+1 , CnH2n+1O-, CmH2m+1O- , CH2=CH(CH2)k-,-CN, -N=C=S,-Hal, bei k = 0-3, 1 = 0-2: m, n = 1-15 sind: Z = -CH2-CH2-, -CH=CH-, -C^C, -COO-, Einfachbindung ist; wobei falls R - CH3,-CN, -Cl, -F ist, 1 0 bis 2 beträgt, als Komponenten eines flüssigkristallinen Materials. Das erfindungsgemäße flüssigkristalline Material enthält wenigstens zwei Komponenten, von denen wenigstens die eine ein flüssigkristallines Derivat des stickstoffhaltigen heterozyklischen Systems der allgemeinen Formel 1 in einer Menge von 1 bis 50 Masse-% darstellt. Novel liquid-crystalline derivatives of nitrogen-containing heterocyclic systems of the general formula R -A -Z-A -R (1) in which R and R are simultaneously or independently CnH2n+1, -CmH2m+1, CnH2n-1O-, CmH2m-1O-, CH2=CH(CH2)k-, -CN, -N=C=S- or -Hal, where k = 0-3, l = 0-2; m and n = 1-15: Z = -CH2-CH2-, -CH=CH-, -C IDENTICAL C-, -COO- or a single bond; where, if A is , A is ; if A is , A is , R is -CH3, -CN, -Cl or -F, and l is 0 to 2, are proposed as components of a liquid-crystalline material. The liquid-crystalline material according to the invention contains at least two components, of which at least one is a liquid-crystalline derivative of the nitrogen-containing heterocyclic system of the general formula 1 in an amount from 1 to 50% by weight.
