Abstract :

Past few decades have witnessed tremendous growth in the field of stateof- art materials which can sense, feel and behave smartly. This will significantly enhance the quality of human living standards and will provide them a more sustainable and secure future. Various state-of-art materials such as photochromic materials1,2, e-paper3, information storage devices4, electrochromic materials5�7, ferroelectric polymers8,9 etc have been reported till the date. In this series, we have also attempted to synthesize a novel Metallo-supermolecular Mn(II) polymer of tridentate O, N, O Schiff�s base ligand with the aim to replace the previously adopted complex and expensive smart materials. A facile synthetic route has been used to synthesize ligand and its hybrid Tb-polymer. The ligand has been fully characterized by FT-IR, 1H-NMR, H-H COSY NMR. Further Job�s method of complexation establishes the 1:1 metal-ligand stoichiometry. The photophysical properties and diffraction study (XRD) has been compared and discussed for both ligand and polymer. Additionally, the morphological study namely FESEM, AFM, EDX, XPS and BET of the polymer has been performed which revealed its surface morphology. Thermal properties of the Tb-poly show its stability up to 530oC. Finally, the electrochemical properties using cyclic voltammetry and the current-voltage relationship of Tb-poly device fabricated on ITO substrate, has been observed to realize the practical applications of this Tb-hybrid polymer in the field of non-volatile memristive devices.
