## Description

- description: Electropolymerization is an important technique for surface functionalization
    owing to its convenient and controlled synthetic pathways. The in-situ synthesis
    of metallo-supramolecular polymers (MSPs) utilizing coordination-driven metal
    ions and coordinating ligands as well as studying their potential applications
    using electropolymerization have been less explored. Herein, we demonstrated the
    formation of MSPs on a pre-terpyridine-functionalized indium tin oxide (ITO) glass
    substrate by using Fe(III) ions and 4′,4′′′′-(1,4-phenylene)-bis(2,2′:6′,2′′-terpyridine)
    ligand. By providing an anodic potential, polymer growth occurred due to the strong
    coordination between the reduced metal ions (Fe(II)) and the bis-terpyridine ligand.
    The formation of the polymer was evident from the growth of the corresponding
    peaks in the cyclic voltammogram and UV-vis spectral profile. The surface morphology
    was characterized using atomic force microscopy (AFM). The electrochromic (EC)
    properties of the electropolymerized MSP (EP-MSP) were studied by utilizing the
    metal-to-ligand charge-transfer color band of the redox-active Fe(II)-(terpyridine)2
    unit present in the MSP backbone. It was observed that the film exhibited an optical
    switching coloring time of 2.1 s and 5.7 s for bleaching, a transmittance change
    of 54%, and a coloration efficiency of 142.6 cm2 C−1.
