Abstract

Nematic materials - produced from substituted benzoyl chlorides and substituted phenols. Cpds. of formula: (where R1 and R2 are CnH2n+1-, CnH2n+1O- and CnH2n+1OCOO-groups) are used in systems in which the preferential orientation of these cpds. can be controlled by magnetic or electric fields, temp. gradients etc. Pref. 2 or more cpds. (I) are mixed or cpds (I) or their mixtures are mixed with further crystalline-liquid or non-crystalline liquid components. (I) are prepared by esterification of substd. benzoyl chlorides with substd. phenols.
