Embodiment 1
[0026] A fluorescent porous material, the chemical formula is C26H16N7O9Cd2, the main ligand is 1,3,5-triimidazolylbenzene, the auxiliary ligand is butenedioic acid, and the solvent is N,N-dimethylformamide;
[0027] Its preparation method is as follows:
[0028] Step 1: weighing and mixing 1,3,5-triimidazolylbenzene, butenedioic acid, and cadmium nitrate tetrahydrate according to a molar ratio of 3:5:1 to obtain a mixture A;
[0029] Step 2 Put mixture A into a container containing N,N-dimethylformamide as a solvent, the ratio of mixture A to N,N-dimethylformamide is 0.05 mmol: 6.00 ml, Ultrasonic treatment for 10 minutes, stirring evenly, to obtain the mixed solution B;
[0030] Step 3: put the mixed solution B obtained in step 2 into the reaction kettle, seal it, and carry out a constant temperature solvothermal reaction at 95° C., the reaction time is 72 hours, and naturally cool to room temperature to obtain light yellow block crystals;
[0031] like figure 1 As shown,...
Embodiment 2
[0036] In this example, the fluorescent porous material obtained in Example 1 was used to detect low-concentration paraquat.
