Abstract:
Fluorinated naphthalene compounds are new. Fluorinated naphthalene compounds (I) of formula (1) are new. R1, R2 = H, 1-12C alkyl or 2-8C alkenyl, optionally having a non-terminal CH2 group replaced by -O-, -C(=O)O- or a CH2 group replaced by -Ctriple bondC-, cyclopropan-1,2-diyl or cyclobutan-1,3-diyl and/or H-atoms are replaced by F whereby R1, R2 are not simultaneously H; M1, M2 = -C(=O)O-, -CH2O-, -CC-, -CH2CH2,-, -(CH)2)4-, -CF2CF2, -CF2O-, or a single bond; E1-E2 = C=CH- or CHCH2-; m, n = 0-2; m+n = 0-2; p = 0 or 1; A, B = phenylen-1,4-diyl, optionally substituted by F, cyclohexan-1,4-diyl, optionally mono- or disubstituted by F, cycohexan-1,4-diyl , optionally monosubstituted by F or 1,3-dioxan-2,5-diyl Independent claims are included for: (1) a liquid crystal medium (II) containing a compound (I) and; (2) a liquid crystal display containing the medium (II).
