ABSTRACT

Among the metallic elements, zinc and most of its compounds find extensive applications in a wide variety of fields. The metal reacts with numerous elements, compounds, proteins, nucleic acids, etc., and the resultant unique complexes in turn take part in metabolism, regulation of genetic information expression, storage, synthesis, and action on peptide hormones. The complexes of zinc are broadly classified as metal complexes, mixed-ligand complexes that include Schiff-based complexes and drug complexes. All these unique products exhibit interesting chemistry and show several biological activities besides having applications in different areas of science and technology. The zinc-based metal-organic framework produces many new molecules that have three-dimensional porous structures and are useful in the synthesis of high-selectivity catalysts and visible-light absorbing photocatalysts. The latter are used in pollution control measures such as organic waste degradation, carbon dioxide reduction, etc.
