The synthesis, characterization and liquid crystal properties of new seven ligands (L1-L7) and their Cu(II)complexes as well as Ni(II) and VO(IV) for L5.The ligands and their complexes have been characterized by IR,1H-NMR, mass spectroscopy and elemental analysis .The liquid crystalline properties of the ligands and the related complexes were studied by differential scanning calorimetry (DSC) and by using a polarizing microscope (POM) equipped with a heating and cooling stage .All the ligands and their complexes exhibit liquid crystalline behavior .
