The synthesis, liquid crystalline and optical properties of copper (II), oxovanadium (IV) and gadolinium (III) complexes derived from polar Schiff’s bases viz., N-(4-n-hexadecyloxysalicylidene)-4′-substituted anilines with methoxy, fluoro and chloro substituents in the 4-position of N-aryl moiety are presented. All the ligands exhibited smectic A phase except methoxy homolog which exhibited nematic phase. Majority of the complexes exhibited smectic A phase with some of them exhibiting smectic E phases. The UV–Visible and photo-luminescent properties of the ligands and complexes are also discussed.
