Fluorinated Analogues of Liquid Crystals 1. Analogues of 4-Methoxybenzylidene-4'-Butylaniline with Perfluorinated Alkyl- and Alkoxy-Groups

For the first time the MBBA analogues comprising of perfluorinated methoxy- and/or n-butyl groups have been synthesized and their mesomorphic properties have been studied. It has been shown that introduction of fluorine atoms into at least one of the substituents causes the appearance of a smectic mesophase, and that the compound comprised of both CF3O and n-C4F9- groups possesses no mesomorphic properties.
