Abstract

Nouveaux composés destinés à être incorporés dans un mélange ferro-électrique à cristaux liquides smectiques, de formule (I) dans laquelle R1 et R2 sont indépendamment H, R, RO1 ROOC, RCOO, RCOOCH(CH3)COO ou bien COOCH(CH3)COOR (R = alkyle) ou CN ou encore halogène. Chacun des noyaux peut-être l'un des noyaux (III) qui peut être substitué, B, C, D sont des groupes de liaison ou des liaisons simples, X, Y, Z sont chacun différents et sélectionnés parmi -O-, COO, OOC, CH2 ou CH(W) où W est alkyle, phényle, cyclohexyle ou CN; b, c, d, e, z et également les noyaux (IV) et (V) présentent la même configuration de substitution latérale. Sont également décrits des mélanges férro-électriques contenant ces composés, qui présentent des phases S*c à la température ambiante.
