Embodiment 1
[0010] The synthesis of embodiment 1 complex:
[0011] 0.1mmol of TbCl 3 ·6H 2 O (0.0374g) and 0.1mmol of tpma (0.029g) were each dissolved in 5ml of anhydrous methanol, mixed the above two solutions, stirred at room temperature for 2 hours and then filtered, and the beaker containing the filtrate was placed in a beaker filled with isopropyl ether In the container, Tb(tpma)Cl was obtained by gas-liquid interface diffusion method 3 Complexes. Then add 0.1mmol of Tb(tpma)Cl 3 (0.0555g) and 0.1mmolK 3 [W(CN) 8 ] (0.05lg) was configured into an aqueous solution, stirred at room temperature for 2 hours and then filtered. The filtrate was allowed to stand in the air and volatilized slowly, and the target product could be obtained after about two weeks. The calculated yield was 32% based on the metal Tb element content.
Embodiment 2
[0012] The infrared spectrometry of embodiment 2 complexes:
[0013] The infrared spectrum of the complex was determined by the KBr tablet method, with a Nicolet330FT-IR infrared spectrometer at 4000-500cm -1 Recorded within the range, see the specific peak value figure 1 .
