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