Embodiment 1
[0022] Using the mixed ligand strategy, 34 mg of L organic ligands containing thiazole functional groups and 82 mg of terphenyldimethyldicarboxylic acid ligands were put into a reaction vessel filled with 100 mL of N,N-dimethylformamide solution, so that It was fully dissolved, and then 108 mg of zirconium tetrachloride and 5.5 mL of acetic acid were added, ultrasonically dissolved, and reacted at 90° C. for 72 hours. After the reaction was completed, cool to room temperature and collect the precipitate by centrifugation. The obtained precipitate was washed three times with N,N-dimethylformamide and ethanol respectively to obtain a yellow-green powder with a yield of about 40.2%.

[0024] Using the mixed ligand strategy, 34 mg of L organic ligands containing thiazole functional groups and 82 mg of terphenyldimethyldicarboxylic acid ligands were put into a reaction vessel filled with 100 mL of N,N-dimethylformamide solution, so that It was fully dissolved, and then 108 mg of zirconium tetrachloride and 5.5 mL of acetic acid were added, ultrasonically dissolved, and reacted at 100° C. for 72 hours. After the reaction was completed, cool to room temperature and collect the precipitate by centrifugation. The obtained precipitate was washed three times with N,N-dimethylformamide and ethanol respectively to obtain a yellow-green powder with a yield of about 56.8%.
example 3
[0026] Using the mixed ligand strategy, 34 mg of L organic ligands containing thiazole functional groups and 82 mg of terphenyldimethyldicarboxylic acid ligands were put into a reaction vessel filled with 100 mL of N,N-dimethylformamide solution, so that After it was fully dissolved, 108mg of zirconium tetrachloride and 5.5mL of acetic acid were added, ultrasonically dissolved, and reacted at 120°C for 72 hours. After the reaction was completed, cool to room temperature and collect the precipitate by centrifugation. The obtained precipitate was washed three times with N,N-dimethylformamide and ethanol respectively to obtain a yellow-green powder with a yield of about 38.9%.
