Abstract

Des composés ont la formule (I), dans laquelle R1 et R2 représentent indépendamment l'un de l'autre R, OR, OCOR, COOR ou OCOOR; R répresente un groupe alkyle ayant entre 1 et 15 atomes de C, où un ou plusieurs groupes CH2 non adjacents et non liés à O peuvent également être substitués avec -O-, -CO-, -O-CO-, -CO-O-, -CH halogène, -CHCN- et/ou -CH=CH-; A1, A2 et A3 représentent indépendamment les uns des autres 1,4 phénylène ou trans-1,4-cyclohexylène; m, n et o sont égaux à 0 ou 1; m+n+o est égale à 0, 1 ou 2; Z1 et Z2 représentent indépendamment l'un de l'autre -CH2-O-, -OCH2-, -CH2CH2- ou une liaison simple; et X représente F, Cl, Br, J ou CN. Dans les conditions décrites dans la première revendication, ces composés peuvent être utilisés comme composants de phases de cristaux liquides ferro-électriques.
