Paramagnetic nematic liquid crystals with an iron core

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.
