Abstract
Liquid crystals (LCs) containing a trifluoromethylamino group are prepared by the cross-coupling reaction of p-bromo-substituted-(hetero)aryl(trifluor omethyl)amines that are derived from the corresponding dithiocarbamates thr ough oxidative desulfurization-fluorination. The novel LCs are shown to exh ibit mainly a smectic phase over a wide range of temperatures. Their electr o-optical properties as a component of nematic LCs are compared with those of the corresponding methylamines.
