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

A preparation method of a metallo-supramolecular polymer, comprising:

• mixing diphenylamine, N-bromosuccinimide and a first organic solvent to perform a bromination reaction, thereby to obtain bis(4-bromophenyl)amine;
• mixing the bis(4-bromophenyl)amine, an X-R compound, a first alkali, a first catalyst and a second organic solvent to perform a Ullmann reaction, thereby to obtain a dibromo compound;
• mixing the dibromo compound, bis(pinacolato)diboron, a second alkali, a second catalyst and a third organic solvent to perform a first Suzuki coupling reaction, thereby to obtain a triphenylamine pinacol borate ester compound;
• mixing the triphenylamine pinacol borate ester compound, 5-Br-phenanthroline, a third alkali, a third catalyst and a fourth organic solvent to perform a second Suzuki coupling reaction, thereby to obtain a polydentate organic ligand having a structure of triphenylamine-phenanthroline;
• and
• mixing a solution of the polydentate organic ligand and an aqueous solution of metal salt to polymerize, thereby to obtain the metallo-supramolecular polymer;
