| titleOfInvention | PENTAFLUORETHYLKETONE |
| abstract | Pentafluoroethylketones of formula (I) R-(A1-Z1)m-A2-Z2-A3-CO-C2F5 where R = H or 1-15C alkyl or alkenyl opt. monosubstd. by CN or CF3 or substd. at least once by halogen and opt. with 1 or more CH2 replaced by -O-, -S-, 1,3-cyclobutylene, -CO-, -CO-O-, -O-CO- or -O-CO-O-, such that O atoms are not directly bonded to each other; A1-A3 = (a) trans-1,4-cyclohexylene opt. substd. by 1 or 2 F and opt. with 1 or more non-adjacent CH2 replaced by -O- and/or -S-; (b) 1,4-phenylene opt. substd. by 1 or 2F and opt. with 1 or 2 CH replaced by N; or (c) 1,4-cyclohexylene, 1,4-bicyclo(2,2,2) octylene, piperidin-1,4-diyl, naphthalene-2,6-diyl, decahydro-naphthalene-2,6-diyl, or 1,2,3,4-tetrahydro naphthalene-2,6-diyl; Z1 and Z2 = -CO-O-, -O-CO-, -CH2O-, -O-CH2-, -CH2-CH2-, -CH=CH-, -C=C- or a single bond, opty. with 1 of Z1 and Z2 also being -(CH24- or -CH=CH-CH2-CH2-; and m = 0, 1 or 2. USE/ADVANTAGE - Use of (I) is claimed as a component in a liq. crystal mixt., as are also liq. crystal displays and electro-optical displays contg. such mixts.. (I) are of low viscosity and relatively high dielectric anisotropy and give stable liq. crystal media with broad mesophase range |
