    Abstract: A polydentate organic ligand, a preparation method and an application method thereof, a mnetallo-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 triphenylamrine. 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.

    Abstract: The present disclosure provides a near-infrared (NIR) photothermal catalyst and a preparation method and use thereof. The method includes: mixing a graphene oxide (GO) dispersion and a dehydrating agent to obtain a GO solution; mixing the GO solution and branched polyethyleneimine (PEI) and then drying to obtain a GO-PEI carrier; and mixing the GO-PEI carrier with water and adjusting a pH value to be within a range of 2 to 4.5, adding dropwise a monosubstituted Keggin-type polyoxometalate (POM) aqueous solution, and conducting an ion replacement reaction to obtain the NIR photothermal catalyst, wherein a solute of the monosubstituted Keggin-type POM aqueous solution is K6SiW11Co(H2O)O39 or H4SiW11Ce(H2O)4O39.
