Abstract
The invention relates to novel compounds of formula R1-A1-Z1-A2-Z2-A3-R2 in which Z1 and Z2 are laterally substituted cyclohexane and cyclohexene rings such as (2), (3), (4), (5), (6), (7), (8), (9). The compounds are useful as components of liquid crystalline mixtures for display applications.
Claims
1. Liquid crystalline compounds represented by general formula 1 
in which R1 and R~ are the same or different and represent a terminal group Y-(CH2)n-(O)m-(CH2)1(-(O)r(CH2)p- or Y-(CH2)n-CH=CH-(CH2)p-, where Y is an H, F, or Cl atom or a CN or OCF3 group, n, p and k assume values from 0 to 7, while m and I denote 0 or 1; Z1 denotes a ring of the formula chosen from the set comprising formulae 4,5,8, 9, ∑2 denotes a single bond or a ring chosen from the set comprising formulae 4,5,8, 9 and at the same time the position of cyclohexene rings Z, and Z-. in relation to other neighboring rings is always such that their double bond is not conjugated with an aromatic ring; Y, in formulae 4,5,8 and 9 denotes a F, Cl atom or a CN group; A, A2, A, denote a single bond or a fragment from the set comprising formulae from 10 to 18, where X,, X2, Xa and X4 are independent and denote an H or F atom, while B and B, denote a single bond or a CH2-CH2, C=C, CH=CH, OCH2, CH2O bridge group.
2. Liquid crystalline mixtures containing at least two compounds and at least one of them is a compound of general formula 1,
R*ι-Aι---.^-A2---^-A3-K2 1 in which R1 and R2 are the same or different and represent a terminal group Y-tCH^O^-CCH^^OHCHjJp- or Y-(CH2)n-CH-=CH-(CH2)p-, where Y is an H, F, or Cl atom or CN, OCF3 group, n, p and k assume values from 0 to 7, while m and I denote 0 or 1; Tr. denotes a ring of formula chosen from the set comprising formulae 4,5,8, 9, Z2 denotes a single bond or a ring chosen from the set comprising formulae 4,5,8, 9 and a position of cyclohexene rings Z, and Z-. in relation to other neighboring rings is always such that their double bond is not conjugated with an aromatic ring; Y1 in formulae 4,5,8 and 9 denotes a F, Cl atom or a CN group; A, A2< A3 denote a single bond or the fragment of a formula from the set comprising formulae from 10 to 18, where X„ X2, X3 and X4 are independent and denote an H or F atom, while B and B1 denote a single bond or a CH2- CH2, C≡C, CH=CH, OCH2 or CH2O bridge group.
3. A display consisting of two parallel plates, at least one of which is made of transparent material, supporting the electrodes, aligning and/or isolating layers and/or colored filters, between which a liquid crystalline material is used, characterized by the fact that said liquid crystalline material is a mixture as descriebed in claim 2.
