Synthesis of VO (IV) Complexes and Study of their Liquid Crystalline Behavior

The synthesis and characterization of new homologous series of VO(IV) complexes derived from 4 (4 – Chloro benzoyloxy) – 2 – hydroxyl benzylidine – 4 – alkoxy aniline (where the alkoxy chain is OCnH2n+1 and n=1-7, 9,10)are reported. The liquid crystalline properties and phase transitions were studied using polarized hot stage optical microscopy and differential scanning calorimetry (DSC) for the ligands and their complexes.
