[0037] The preparation method of the cadmium compound with cationic skeleton, 2,5-two (4-pyridyl) pyrimidine ligand and Cd (CH 3 COOH) 2 2H 2 Put O together in a 10ml small glass bottle, add N,N'-dimethylformamide (DMF) organic solvent, add 5 drops of HNO 3 solution, its pH was measured to be 7.5, and the solution was clear at this time. Heat the sealed vial to 105°C in an air blast drying oven for 7 days, and then cool it down to room temperature at a rate of 8°C / h. At this time, colorless block crystals are precipitated in the vial. , and then washed 6 times wi...
Embodiment 2
[0041] Compound is the same as Example 1, and the different preparation methods and uses are:
[0042] The preparation method of the cadmium compound with a cationic skeleton comprises 2,5-bis(4-pyridyl)pyrimidine ligand and precursor Cd(CH 3 COOH) 2 2H 2 Put O together in a 10ml small glass bottle, the molar ratio of the ligand to the cadmium precursor is 1:1-5, add N,N'-dimethylformamide organic solvent, drop 10 drops of HNO 3 solution, its pH was measured to be 7, and the solution was clear at this time. Heat the sealed vial to 150°C in a blast drying oven for 15 days, then cool down to room temperature at a rate of 10°C / h. At this time, colorless block crystals are precipitated in the vial , and then washed 8 times with DMF solution to obtain pure colorless crystals, yield: 80%.
