Embodiment 1
[0026] In a polytetrafluoroethylene-lined stainless steel kettle, accurately weigh the precursor ligand 2-hydroxy-1,3,5-benzenetricarboxylic acid and 4-4bpy and add deionized water to the sample bottle at a molar ratio of 1:2:2000 Mixed in the medium, ultrasonically mixed uniformly to get the mixed solution 1 for later use; accurately measure the diethylamine solution and add it to the sample bottle in step 2, wherein the concentration of the diethylamine solution is 1mmol / L, and the volume ratio of the mixed solution 1 Mix it in a ratio of 1:200-7:100 and add it to the sample bottle in the mixed solution 1, ultrasonically dissolve and mix evenly, and then stand for use, which is the mixed solution 2. Accurate pipetting of MnCl 2 .4H 2 The O solution was added dropwise to the sample bottle in step 3 to obtain a mixture 3, and the mixed solution was ultrasonically reacted for use. The MnCl 2 .4H 2 The concentration of O solution is 1mmol / L, MnCl 2 .4H 2 The volume ratio o...
