Embodiment 1
[0027] The synthetic method of mononuclear dysprosium magnetic complex comprises the following steps:
[0028] Step 1, DyCl 3 ·6H 2 O (0.2mmol) and organic ligand TPA (0.2mmol) were stirred and mixed in 4mL of anhydrous methanol solution, and allowed to react for 10min;
[0029] Step two, HOPhCl 2 NO 2 (0.4mmol) was dissolved in 12mL of acetonitrile, triethylamine (0.8mmol) was added thereto, allowed to react for 5min, and then the mixed solution in step 1 was added to produce a yellow precipitate;
[0030] Step 3: Dissolve the yellow precipitate in step 2 in 4 mL of dichloromethane, transfer it to a test tube, slowly drop in 10 mL of n-hexane to form a two-phase layer, and let it stand for 2 days to obtain the crystal of the mononuclear dysprosium-based magnetic complex.
[0031] The yield of the mononuclear dysprosium magnetic complex prepared in this example was 57.8%.
Embodiment 2
[0033] The synthetic method of mononuclear dysprosium magnetic complex comprises the following steps:
[0034] Step 1, DyCl 3 ·6H 2 O (0.2mmol) and organic ligand TPA (0.2mmol) were stirred and mixed in 6mL absolute ethanol solution, and allowed to react for 10min;
[0035] Step two, HOPhCl 2 NO 2 (0.4mmol) was dissolved in 5mL acetonitrile, triethylamine (0.6mmol) was added thereto, allowed to react for 5min, and then the mixed solution in step 1 was added to produce a yellow precipitate;
[0036] Step 3. Dissolve the yellow precipitate in step 2 in 5 mL of dichloromethane, transfer it to a test tube, slowly drop in 15 mL of n-hexane to form two-phase separation, and obtain the crystal of the mononuclear dysprosium-based magnetic complex after 2 days.
[0037] The yield of the mononuclear dysprosium magnetic complex prepared in this example was 58.4%.
[0038] The characterization of the mononuclear dysprosium magnetic complex prepared in this example is as follows:
