Abstract
Over the past few years some interest has been devoted to the study of mesogenic metal-containing compounds [1]. One of the aspects that makes them different from typical organic liquid crystals is the great variety of molecular geometries that can be obtained by introducing metals into the chemical structure: rod-like, disc-like, brick-like, open-book or K shapes among others [2–6]. Similar to organic mesogens, these compounds exhibit either calamitic or discotic mesophases. In this work we will present mainly dielectric studies on some metallomesogenic compounds, both chiral and non-chiral with special emphasis in those that show ferroelectric behavior. Metal-containing liquid crystals open this field not only to a significant number of new structures but also add to the ferroelectric behavior other properties inherent to the presence of metals in the structure, such as magnetism, as well as the use of new methods of characterization (for example EPR [7]).
