in which
R1 and R2 each, independently of one another, denote H, halogen, —CN, —SCN, —SF5, —CF3, —CHF2, —CH2F, —OCF3, —OCHF2 or an alkyl group having 1 to 15 C atoms, which is optionally monosubstituted by CN or CF3 or at least monosubstituted by halogen and in which optionally one or more CH2 groups, in each case independently of one another, are replaced by —O—, —S—, —CH═CH—, —CF═CF—, —CF═CH—, —CH═CF—,
—CO—, —CO—O—, —O—CO— or —O—CO—O— in such a way that neither O nor S atoms are linked directly to one another,
>Y1—Y2— denotes >C═CH— or >CH—CH2—,
L1 and L2 are both F,
each, independently of one another, and, if present more than once, these also independently of one another, denote
(a) a trans-1,4-cyclohexylene radical, in which one or two non-adjacent CH2 groups are optionally replaced by —O— and/or —S,
(b) a 1,4-cyclohexenylene radical,
(c) a 1,4-phenylene radical, in which one or two non-adjacent CH groups are optionally replaced by N,
(d) naphthalene-2,6-diyl, decahydronaphthalene-2,6-diyl or 1,2,3,4-tetrahydronaphthalene-2,6-diyl, or
(e) 1,4-bicyclo[2.2.2]octylene, 1,3-bicyclo[1.1.1]pentylene or spiro[3.3]heptane-2,6-diyl,
wherein in
(a) and (b), one or more —CH2— groups, independently of one another, are optionally replaced by a —CHF— or a —CF2— group, and in (c) and (d), one or more —CH═ groups, independently of one another, are optionally replaced by —CF═, —CCl═, —CBr═, —C(CN)═, —C(CH3)═, —C(CH2F)═, —C(CHF2)═, —C(OCH3)═, —C(OCHF2)═ or —C(OCF3)═,
Z1 and Z2 each, independently of one another, and, if present more than once, these also independently of one another, denote a single bond, —CH2—CH2—, —CF2—CH2—, —CH2—CF2—, —CF2—CF2—, —CH═CH—, —CF═CF—, —CF═CH—, —CH═CF—, —C≡C—, —COO—, —OCO—, —CH2O—, —OCH2—, —CF2O—, or —OCF2—, or a combination of two of these groups, where no two O atoms are bonded to one another, and
n and m each independently denote 0, 1, 2 or 3, where
(n+m) denotes 0, 1, 2 or 3.

Abstract

Disclosed are furochroman compounds of formula I liquid-crystal media which contains the compounds of formula I, and the use of the media in electro-optical displays, in particular in VAN LCDs.

A compound of formula I

in which
R1 and R2 each, independently of one another, denote H, halogen, —CN, —SCN, —SF5, —CF3, —CHF2, —CH2F, —OCF3, —OCHF2 or an alkyl group having 1 to 15 C atoms, which is optionally monosubstituted by CN or CF3 or at least monosubstituted by halogen and in which optionally one or more CH2 groups, in each case independently of one another, are replaced by —O—, —S—, —CH═CH—, —CF═CF—, —CF═CH—, —CH═CF—,
—CO—, —CO—O—, —O—CO— or —O—CO—O— in such a way that neither O nor S atoms are linked directly to one another,
>Y1—Y2— denotes >C═CH— or >CH—CH2—,
L1 and L2 are both F,
each, independently of one another, and, if present more than once, these also independently of one another, denote
(a) a trans-1,4-cyclohexylene radical, in which one or two non-adjacent CH2 groups are optionally replaced by —O— and/or —S,
(b) a 1,4-cyclohexenylene radical,
(c) a 1,4-phenylene radical, in which one or two non-adjacent CH groups are optionally replaced by N,
(d) naphthalene-2,6-diyl, decahydronaphthalene-2,6-diyl or 1,2,3,4-tetrahydronaphthalene-2,6-diyl, or
(e) 1,4-bicyclo[2.2.2]octylene, 1,3-bicyclo[1.1.1]pentylene or spiro[3.3]heptane-2,6-diyl,
wherein in
(a) and (b), one or more —CH2— groups, independently of one another, are optionally replaced by a —CHF— or a —CF2— group, and in (c) and (d), one or more —CH═ groups, independently of one another, are optionally replaced by —CF═, —CCl═, —CBr═, —C(CN)═, —C(CH3)═, —C(CH2F)═, —C(CHF2)═, —C(OCH3)═, —C(OCHF2)═ or —C(OCF3)═,
Z1 and Z2 each, independently of one another, and, if present more than once, these also independently of one another, denote a single bond, —CH2—CH2—, —CF2—CH2—, —CH2—CF2—, —CF2—CF2—, —CH═CH—, —CF═CF—, —CF═CH—, —CH═CF—, —C≡C—, —COO—, —OCO—, —CH2O—, —OCH2—, —CF2O—, or —OCF2—, or a combination of two of these groups, where no two O atoms are bonded to one another, and
n and m each independently denote 0, 1, 2 or 3, where
(n+m) denotes 0, 1, 2 or 3.
