    摘要: The invention relates to bisphenyl thiocompounds of formula (I), wherein X1 to X5 independently represent H, Cl, F, OH, SH, R, —OR and —SR, wherein R is an organic radical with 1 to 18 C atoms, which can be an alkyl or alkenyl radical that can also contain —O—, —S— instead of a one to four non-adjacent CH2 groups and that can be substituted once or multiple times by —OH, —SH or halogen, an unsubstituted phenyl, cyclohexyl or cyclohexylmethyl radical or substituted by one or up to three alkyl groups with a total of 1 to 9 C atoms in which a CH2 group may be replaced by —O—, provided that at least 3 of the radicals X1 to X5 are; Y1 to Y5 independently have the meaning cited for X1 to X5 and Z represents an &agr;, &ohgr;-alkylene group with 2 to 18 C atoms in which one to three CH2 groups may be substituted by —O— or —S— and 1,4-cyclohexandimethyl group or a simple bond. The invention also relates to the use of said compounds as lubricants.

    摘要: Novel tetrasubstituted methane derivatives of the general formula C[--Sp--M--R].sub.4 in which the radicals --Sp--M--R are the same or different, in which Sp is a spacer group selected from an alkylene or alkenylene radical which is unsubstituted or monosubstituted by halogen, --CN or --CF.sub.3 or one or two non-adjacent CH.sub.2 groups may be replaced by --O--, --CO--, --COO--, --OOC--, --CONH-- or --OCOO--, or is a single bond; R is selected from hydrogen, halogen, --CN, --CF.sub.3, --OCF.sub.3, --NO.sub.2, --N(CH.sub.3).sub.2, an alkyl or alkenyl radical which is unsubstituted or monosubstituted or polysubstituted by --CN, --NH.sub.2, --CF.sub.3 or halogen and in which one or more non-adjacent CH.sub.2 groups may be replaced by the radicals --O--, --CO--, --OOC--, --COO-- or OCOO--; and M is a mesogenic group. Due to their liquid crystal properties, the novel compounds are eminently suitable for use in liquid crystalline media.
