Abstract

Metal-containing liquid crystals are of great current interest due to their interesting electrooptic and magnetic properties. Paramagnetic liqid crystals, whose director can be oriented parallel or perpendicular to a magnetic field are particularly interesting and examples have been synthesized containing copperand vanadium. Here, examples of these materials containing iron(III) are reported, and are found to exhibit a paramagnetic nematic mesophaseand, in some cases, a smectic C phase as well.
