Liquid-Crystalline Behavior in Some Homologous Series of Beta-Diketones and a Few of Their Copper(II) and Palladium(II) Complexes
The synthesis and mesomorphic properties of three homologous series of beta-diketones as well as one series each of copper(II) and palladium(II) complexes are reported. The beta-diketones exhibit a smectic A phase while both the copper(II) and palladium(II) complexes show only a metastable nematic phase. Optical microscopy and differential scanning calorimetry have been used to characterize the mesophases.
