Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.

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 ? 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.
