Abstract
(EN)
This invention describes compounds of formula (I) wherein R is C1-16 alkyl or alkoxy; X is selected from F and Cl and indicates that one or more of the phenyl rings may be laterally substituted; x is selected from 0-3; A and B are independently selected from CO2, OCO, $m(Z)C and single bond; R1 and R2 are independently selected from H and C1-16 alkyl provided that R1 and R2 are different; n is 0 or 1 provided that if n is zero then B is single bond. These compounds may be used as dopants suitable for use in ferroelectric liquid crystal mixtures.
(FR)
La présente invention concerne des composés représentés par la formule générale (I). Dans cette formule, R est C1-C16 alkyle ou alcoxy. X est choisi entre F et Cl et indique qu'un ou plusieurs cycles phényle peuvent être latéralement substitués. x est un entier allant de 0 à 3. A et B sont choisis indépendamment parmi CO2, OCO, C$m(Z)C et une liaison simple. R1 et R2 sont choisis indépendamment parmi H et C1-C16 alkyle sous réserve que R1 et R2 soient différents. n vaut 0 ou 1 sous réserve que si n vaut zéro, B est une liaison simple. Ces composants utilisables comme dopants conviennent à l'utilisation dans les mélanges pour cristaux liquides ferroélectriques.
