Abstract The synthesis, characterization and investigation of a new liquid crystalline series of ester containing aroylhydrazones with a lateral hydroxyl group, N-[4-(4′-alkoxy) benzoyloxy-2-hydroxy-benzylidene]-N′-[4 ″-alkoxybenzoyl] hydrazine (C m, n LH), with the same or different peripheral alkoxy chains, and some of their nickel (II) and copper (II) complexes are described. All the ligands, except those with no terminal chains on either ...
