The invention discloses a copper pyrazole-3-carboxylate polymer and a preparation method thereof. The preparation method comprises the following steps: 1, weighing 0.5-1 mmol of copper nitrate trihydrate, and dissolving the copper nitrate trihydrate in 4-8 mL of distilled water to prepare a copper nitrate solution; 2, weighing 0.5-1 mmol of pyrazole-3-carboxylic acid, and dissolving the pyrazole-3-carboxylic acid in 3-6 mL of anhydrous ethanol to prepare a pyrazole-3-carboxylic acid solution; 3, weighing 0.5-1 mmol of imidazole, and dissolving the imidazole in 2-4 mL of anhydrous ethanol to prepare an imidazole solution; 4, weighing 0.5-1 mmol of sodium hydroxide, and dissolving the sodium hydroxide in 1-2 mL of distilled water to prepare a sodium hydroxide solution; and 5, adding the solutions prepared in step 1, step 2, step 3 and step 4 into a polytetrafluoroethylene reaction kettle inner container, sleeving a stainless steel reaction kettle jacket, placing the obtained reaction kettle in a 80 DEG C oven, carrying out a reaction for 48-72 h, cooling the kettle to room temperature according to 10 DEG C / h after the reaction ends, allowing the reaction product to stand for 12 h, opening the kettle to obtain a light blue solution, and filtering the light blue solution on a filter paper to obtain dark blue block crystals in order to obtain the copper pyrazole-3-carboxylate polymer. The method has the advantages of simple process, low cost and good repeatability.
Description
technical field [0001] The invention belongs to the technical field of polymer preparation, in particular to a pyrazole-3-carboxylic acid polymer and a preparation method thereof. Background technique [0002] In recent years, the types and numbers of transition metal polymers have increased rapidly. People use organic small molecule ligands with special structures and properties and metal ions to synthesize coordination supramolecules through coordination bonds or other weak interactions. Unique in structure and performance. However, there are few reports on polymers of pyrazole-3-carboxylic acid. Because pyrazole-3-carboxylic acid has fewer coordination sites and simple coordination methods, most of the complexes reported are small molecule complexes, and there are few reports on polymers. Therefore, we use pyrazole-3-carboxylic acid The synthesis of polymers with this small molecular organic ligand provides a certain basis for the research of such ligands in polymers. ...
