The synthesis of a series of bidentate Schiff's bases; 3,5-bis(3',4',5'-trialkoxybenzyloxy) phenyl-2-N-(3-hydroxypropy)iminopropyl ketone, and their dicopper complexes are reported. The liquid crystalline behaviour of these dicopper complexes was studied by DSC, polarized optical microscopy and X-ray diffraction. The phases were characterized and identified as hexagonal columnar (D-h) phases, which are typical of disc-like molecules.
