Abstract
A polydentate organic ligand, a preparation method and an application method thereof, a metallo-supramolecular polymer and a preparation method thereof are provided. A structure of triphenylamine is combined with a structure of phenanthroline to serve as the polydentate organic ligand, which takes advantages of a large-volume distortion structure and excellent electroactivity of the triphenylamine. The polydentate organic ligands have good solubility, which provides lower-cost and diversified methods for preparing the metallo-supramolecular polymers. Meanwhile, the phenanthroline has a rigid structure and a conjugated large π bond in its molecule, which facilitates chelating coordination with metal ions to form a stable compound. Therefore, the polydentate organic ligand enables the metallo-supramolecular polymer to have good transferability, stable electroactivity, and high conversion speed, i.e., fast response speed, excellent electrochromic cycling stability and long service lifetime.
