Abstract
New anisotropic compounds suitable for use in LC-display devices are disclosed and claimed. The new compounds are cyclohexyl cyclohexylmethyl ethers of formula (1): ##STR1## in which X and Y are respectively hydrogen, alkyl group with 1 to 12 C-atoms, alkoxy group with 1 to 12 C-atoms, monoalkylamino group with 1 to 12 C-atoms, nitrile group, nitro group, halogen, or cyclic radical of formula (1a) or (1b): ##STR2## in which R.sup.1 and R.sup.2 represent hydrogen alkyl group with 1 to 12 C-atoms, alkoxy group with 1 to 12 C-atoms, monoalkylamino group with 1 to 12 C-atoms, nitrile group, nitro group or halogen, and Z.sup.1 and Z.sup.2 represent simple covalent bonds or grounds of the formulas --COO--, --OOC--, --CH.sub.2 O-- or --OCH.sub.2, with the requirement that only one of the groups X, Y can be a cyclicradical or formula (1a) or (1b). Also disclosed and claimed are LC-mixtures containing these compounds and methods for their synthesis.
