| abstract | 1,3-Dioxan derivatives of formula R<1>-(A<1>-Z<1>)m-W-(Z<2>-A<2>)n-R<2> (I) with axial fluorine substituents is new, in which W = -(W1)n1-(W2)n2-(W3)n3- or -(W4)n4-Z<3>-(W5)n5-Z<4>-(W6)n6-; W1-W3 = groups of formula (Fcyc) or (diox); n1, n2, n3 = 0 or 1; one of these groups must be (Fcyc) and another must be (diox); W4-W6 = groups of formula (Fcyc), (diox) or (Fdiox), with n4, n5 and n6 = 0 or 1; one of these groups must be (Fdiox); R<1>, R<2> = 1-12C alkyl or alkenyl (optionally substituted with one CN or CF3 group or at least one halogen, and optionally with one or more CH2 replaced by O, S, CO, COO, OCO or OCOO); R<2> may also be F, Cl or CN; A<1>, A<2> = (a) trans-1,4-cyclohexylene (cyc) (optionally with one or more non-adjacent CH2 replaced by O and/or S), (b) 1,4-cyclo-hexenylene, (c) 1,4-phenylene (Pn; optionally with one or two CH groups replaced by N), or (d) 1,4-bicyclo2.2.2octylene, piperidine-1,4-diyl, naphthalene-2,6- diyl or its decahydro- or 1,2,3,4-tetrahydro- derivatives (groups a, b and c may also be substituted with CN or F); Z<1>-Z<4> = -COO-, -OCO-, -CH2O-, -OCH2-, -CH2CH2-, -CH=CH-, -C?=C- or a single bond; m, n = 0, 1, 2 or 3; n1 + n2 + n3 + m + n = 2, 3 or 4; and n4 + n5 + n6 + m + n = 1, 2, 3 or 4. Also claimed are (i) a liquid crystal (LC) medium with at least two LC components, containing at least one derivative (I); and (ii) LC display elements and electro-optical display elements containing such LC media. |
