Synthesis and liquid crystal properties of copper(II) and palladium(II) chelates with new ferrocene-containing enaminoketones

The syntheses of a series of ferrocene-containing β-aminovinylketone complexes with Cu(II) and Pd(II) ions are described in this article. The synthesized ligands and Cu(II) complexes exhibited disordered soft crystal phases upon cooling from the isotropic liquid state, and the Pd(II) complexes showed monotropic smectic C mesomorphism.
