Abstract:
4-[(3,5-Difluoro-4-trifluoromethyl-phenoxy)-difluoro-methyl]-3,5,2'-trifluoro-biphenyl compounds (I), are new. 4-[(3,5-Difluoro-4-trifluoromethyl-phenoxy)-difluoro-methyl]-3,5,2'-trifluoro-biphenyl compounds of formula (I), are new. A1 : 1,4-phenylene, which is optionally up to 4 times substituted by halo, CN, CH 3, CHF 2, CH 2F, OCH 3, OCF 3or OCHF 2and 1-2 CH-groups (optionally substituted by N), cyclohexane-1,4-diyl or cyclohexene-1,4-diyl, in which each optionally 1-2 CH 2groups can be substituted by O or S and/or H or F, bicyclo[1.1.1]pentane-1,3-diyl, bicyclo[2.2.2]octane-1,4-diyl, spiro[3.3]heptan-2,6-diyl, tetrahydropyran-2,5-diyl, 1,3-dioxane-2,5-diyl, 2,5-thiophenediyl or 2,5-selenophenediyl; Z1 : a single bond, CF 2O, CH 2CH 2, CF 2CH 2, CF 2CF 2, CFHCFH, CFHCH 2, (CO)O, CH 2O, C=C, CH=CH, CF=CH or CF=CF, where unsymmetrical connecting links can be oriented in both possible directions; and R1 : 1-15C unsubstituted alkyl, in which rest one or more CH 2groups are replaced by -CC-, -CH=CH-, -CF=CF-, -CF=CH-, -CH=CF-, -(CO)O-, -O(CO)-, -(CO)- or -O- in such a way that O atoms are not linked directly to each other, H, F, Cl, Br, CN, CF 3, OCF 3, SCN, NCS or SF 5. Independent claims are included for: (1) the preparation of (I); (2) a liquid-crystalline medium comprising (I); and (3) an electro-optical display device comprising the liquid crystalline medium.
