Abstract

L'addition concerne des cristaux liquides du type << diester >>, présentant au moins une phase mésomorphe du type nématique, et dont l'anisotropie diélectrique change de signe lorsqu on change la fréquence du champ électrique appliqué au cristal liquide, de part et d'autre d'une fréquence dite << disotropie diélectrique >>. Ils répondent à la formule :
