Polymeric complexes - LXII. Coordination chemistry of supramolecular Schiff base polymer complexes - A review

This review gives an account of the coordination chemistry of supramolecular Schiff base polymer complexes. The synthesis and structures of Schiff base monomers and their polymer complexes were described. Spectral techniques like (IR, H-1-NMR) and thermal analysis were investigated. ESR spectral data provided information about their structure on the basis Hamiltonian parameters and degree of covalency. The ESR data in connection with the structures and the nature of the bonding in these polymer complexes were investigated. This kind of investigation is fundamentally important to the structural estimation of various metallo-enzymes. The thermal stability was investigated using thermogravimetric analysis. The results showed that the Schiff base polymer complexes are mostly more stable than the homopolymer. The corrosion inhibition efficiency in absence and presence of ligands of aluminium in HCl was studied. The antimicrobial activity of all metal complexes compounds has also been demonstrated.
