| titleOfInvention | Liquid crystalline 3,4,5-tricyanophenyl derivatives |
| abstract | 3,4,5-Tricyanophenyl derivatives of formula I <EMI ID=1.1 HE=30 WI=87 LX=403 LY=620 TI=CF> <PC>may be used as components in liquid crystal media and displays. These compounds exhibit very high dielectric anisotropy ( We ) and therefore can be used in small amounts as dopants to increase the value of We in liquid crystal media. In formula I: <DL TSIZE=10> <DT>R<DD>is F, Cl, CN, NCS, or a straight-chain or branched alkyl group with 1 to 25 C atoms which may be unsubstituted, mono- or polysubstituted by halogen or CN, it being also possible for one or more CH<SB>2</SB> groups to be replaced, in each case independently from one another, by -O-, -S-, -NH-, - N(CH<SB>3</SB>)-, -CO-, -COO-, -OCO-, -OCO-O-, -S-CO-, - CO-S-, -CH=CH-, -CH=CF-, -CF=CF- or -C I C- in such a manner that oxygen atoms are not linked directly to one another; <DT>A<SP>1</SP> and A<SP>2</SP><DD>are each independently 1,4-phenylene (wherein in addition one or more CH groups may be replaced by N),trans-1,4-cyclohexylene (in which, in addition, one or two non-adjacent CH<SB>2</SB> groups may be replaced by O and/or S), 1,4-cyclohexenylene, 1,4-bicyclo-(2,2,2)-octylene, piperidine-1,4-diyl, naphthalene-2,6-diyl, decahydro-naphthalene-2,6-diyl, 1,2,3,4-tetrahydro-naphthalene-2,6-diyl, cyclobutane-1,3-diyl, spiro[3.3]heptane-2,6-diyl or dispiro[3.1.3.1] decane-2,8-diyl, it being possible for all these groups to be unsubstituted, mono-, di-, tri- or tetrasubstituted with alkoxycarbonyl groups with 1 to 7 C atoms, wherein </DL> one or more H atoms may be substituted by F or Cl; Z<SB>1</SB> and Z<SB>2</SB> are each independently -CH<SB>2</SB>O-, -OCH<SB>2</SB>-, -COO-, - OCO-, -CH<SB>2</SB>CH<SB>2</SB>-, -(CH<SB>2</SB>)<SB>4</SB>-, -CF<SB>2</SB>CF<SB>2</SB>-, -CH=CH-, - CF=CF-, -C I C- or a single bond; and m is 0, 1 or 2. |
