Embodiment 1
[0084] Example 1 Tb(ACAC) 3 Preparation of phen
[0085] Use a graduated cylinder to measure 20 mL of absolute ethanol and put it into a 50 mL beaker; weigh 1.5 mmol (about 0.5401 g) of terbium chloride hexahydrate with an electronic balance, put it into the above-mentioned beaker containing ethanol, stir and dissolve for 15 minutes, and heat the system temperature to 40°C;
[0086] Weigh 4.5mmol (about 0.46ml) of acetylacetone and add it dropwise to the above beaker, and continue to stir for 30min (denoted as ligand I system 1);
[0087] Measure 0.46g (0.63ml) of triethylamine and dissolve and dilute it with 5ml of absolute ethanol, then add it dropwise to the Ligand I system. , calculated in the amount of pure triethylamine, the dropping time is 30min; continue to react for 1h (recorded as ligand I system 2);
[0088] Weigh 1.5mmol (0.2973g) 1,10-phenanthroline, add 5mL ethanol to dissolve and dilute, then add dropwise to Ligand I system 2, the temperature of the reacti...
Embodiment 2
[0090] Example 2 Tb(ACAC) 2 (phen) 2 preparation of
[0091] This embodiment is the same as the method used in Example 1, the only difference is that the amount of acetylacetone used is 3.0mmol (0.3003g), the amount of triethylamine is 3.0mmol (0.3036g), and the amount of 1,10-phenanthroline is 3.0 mmol (0.5406 g). The product is denoted as Tb(ACAC) 2 (phen) 2 .
