Novel aggregation-induced emission nitrogen-rich group carboxylate ligand and preparation method thereof

The invention relates to the field of organic synthesis, and provides a novel aggregation-induced emission nitrogen-rich group carboxylate ligand and a preparation method thereof. The problems that the hole diameter of a metal organic skeleton synthesized by an existing ligand including aggregation-induced emission is small, and boundedness is caused in the aspects such as gas adsorption sensing are solved. The preparation method comprises the steps: (1) material mixing is conducted, specifically, a catalyst is added to be evenly mixed to obtain a mixture; (2) the mixture is placed into a container under a protective atmosphere condition, an organic solvent is added for reacting, and then a precursor solution is obtained; (3) the precursor solution is subjected to suction filtration, washed and dried, after being dried, the precursor solution is added with acid to be stirred for reacting, filtered, water-washed and dried, and then a solid intermediate is obtained; and (4) the intermediate is added into an alk
