A polydentate organic ligand has a triphenylamine-pyridine substituted triazole structure with the structural formula I. The polydentate organic ligand having the triphenylamine-pyridine substituted triazole structure and the metal ion are coordinated and driven to synthesize a series of metallo-supramolecular polymers, and the prepared metallo-supramolecular polymers have stable electroactivity, rapid color-switching speeds, and excellent electrochromic performance.

Polydentate organic ligand, metallo-supramolecular polymer, polymer film and preparation method thereof

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.
