Abstract
Six mononuclear ortho-palladated complexes containing amino-acid chelate ligands and azine or azo, imine ligands have been synthesized and characterized by elemental analysis, IR, 1H NMR and 13C NMR. Their thermotropic behaviors and mesogenic properties were studied. The relation between mesogenic properties and molecular structures of complexes were also discussed. As a result, three novel organometallic ferroelectric liquid crystals were found.
