Title
(EN) FLUORO TOLANS AND LIQUID CRYSTALLINE MEDIA
(FR) FLUOROTOLANES ET MILIEUX CRISTALLINS LIQUIDES
Abstract
(EN) Fluoro tolans of formula (I), wherein R1 denotes alkyl with up to 12 carbon atoms wherein one or two non-adjacent CH2 groups may also be replaced by -O-, -O-CO-, -CO-O- and/or -CH=CH-, A is trans-1,4-cycolhexylene or 1,4-phenylene, r is 0 or 1, s is 0 or 1, Q is -CF2- or -OCF2- and - if Y = F and/or L1 = L2 = F - also a single bond, L1 and L2 are H or F, and Y is H, F or Cl are suitable as components of liquid crystalline media.
(FR) On décrit des fluorotolanes de formule (I), dans laquelle R1 représente un alcoyle comprenant au moins 12 atomes de carbone dans lequel un ou deux groupes CH2 non adjacents peuvent également être remplacés par -O-, -O-CO-, -CO-O- et/ou -CH=CH-. A représente le trans-1,4-cyclohexylène ou 1,4-phénylène, r vaut 0 ou 1, s vaut 0 ou 1, Q représente -CH2- ou -OCF2- et, si Y = F et/ou L1 = L2 = F, également une liaison unique, L1 et L2 représentent H ou F, et Y représente H, F ou Cl. Ces fluorotolanes sont utilisables comme composants de milieux cristallins liquides.
