Preparation of Zinc Oxide Nanomaterial using Unsymmetrical Schiff Base Complexes
The unsymmetrical Schiff base Zn(II) complexes Zn(L)(H2O)2, where L is the unsymmetrical tetra-dentate Schiff base ligands of N-(5-bromo-2-hydroxy acetophenone)-N’-(2-hydroxy acetophenone) ethylenediamine (L1) and N-(3,5-dibromo-2- hydroxy acetophenone)-N’-(2-hydroxy acetophenone) ethylenediamine (L2) were synthesized and characterized by physico-chemical and spectroscopic methods. Zinc oxide nanomaterial was obtained followed by calcination at 260oC. The structures of the nano-sized compounds were characterized by Xray powder diffraction and scanning electron microscopy. The thermal stabilities of the complex and nano-sized ZnO particles were studied by thermogravimetric analysis.
