Embodiment 1
[0023] A fluorescent probe complex that simultaneously recognizes phosphate and copper ions in water, its chemical formula is {[Zn(btca)(py) 2 ]} n , wherein btca is 5-carboxybenzotriazole dianion, and py is pyridine; its preparation method steps are as follows:
[0024] 1) Put 0.025 mmol H 2 btca and 0.10 mmol of zinc nitrate hexahydrate were added to 1.0 ml of pyridine and 5.0 ml of distilled water, and added to a 20-ml glass bottle with a screw cap to obtain a mixed solution;
[0025] 2) Seal the above mixture and place it in an oven at 100 o The reaction was performed in a constant temperature oven at C for 24 hours to obtain colorless diamond-shaped bulk crystals. The crystals obtained by filtration were washed three times with distilled water and anhydrous ethanol, respectively, and dried to obtain the target product.
