Embodiment 1

[0028]Preparation of 1-[9-(1H-1,2,4-triazol-1-yl)anthracen-10-yl]-1H-1,2,4-triazole (tatrz) ligand

[0029] The preparation method of 1-[9-(1H-1,2,4-triazol-1-yl)anthracene-10-yl]-1H-1,2,4-triazole of the present invention is characterized in In the "one-pot method", the organic compound is prepared by heating 9,10-dibromoanthracene, triazole, potassium carbonate and copper oxide in a polar solvent; wherein 9,10-dibromoanthracene: three Azole: potassium carbonate: the molar ratio of copper oxide is 2:10:30:1;

[0030]

[0031] In the present invention, the molar ratio of 9,10-dibromoanthracene (I): triazole (II): potassium carbonate: copper oxide is preferably 2:10:30:1; the reaction temperature is 80-200°C, and the reaction time is 12-120 hours .

[0032] The more detailed preparation method of the present invention is as follows:

[0033] A preparation method of 1-[9-(1H-1,2,4-triazol-1-yl)anthracen-10-yl]-1H-1,2,4-triazole is characterized in that, in In a polar solv...

[0037] Cu(ClO 4 ) 2 and 1-[9-(1H-1,2,4-triazol-1-yl)anthracen-10-yl]-1H-1,2,4-triazole (tatrz) in a molar ratio of 1: 1;

[0038] tatrz (0.0312 g, 0.1 mmol) and Cu(ClO 4 ) 2 (0.0370 g, 0.1 mmol) in H 2 O (6 mL) and CH 3 OH (4 mL) was stirred in a mixed solvent at room temperature for half an hour and then filtered, and the filtrate was volatilized at room temperature as yellow rod-shaped crystals analyzed by X-ray single crystal diffraction. Yield: 35% (calculated based on tatrz). Elemental analysis (C 40 h 44 Cl 2 CuN 12 o 14 ) Theoretical value (%): C, 45.70; H, 4.22; N, 15.99. Found: C, 45.75; H, 4.12; N, 15.89.

[0039] Example 2

[0040] The crystal structure was determined using an APEX II CCD single crystal diffractometer, using graphite monochromatized Mokα rays (λ = 0.71073 ?) as the incident radiation, and ω -2 θ Diffraction points are collected by scanning, and the unit cell parameters are obtained by least square method correction. The crysta...

Embodiment 3

[0044] Cu(ClO 4 ) 2 and 1-[9-(1H-1,2,4-triazol-1-yl)anthracen-10-yl]-1H-1,2,4-triazole (tatrz) in a molar ratio of 1: 1;

[0045] We also tried other ratios such as Cu(ClO 4 ) 2 and 1-[9-(1H-1,2,4-triazol-1-yl)anthracen-10-yl]-1H-1,2,4-triazole (tatrz) in a molar ratio of 2: 1, no matter how long the hydrothermal reaction time is, no crystalline compound can be obtained. Therefore Cu(ClO 4 ) 2 and 1-[9-(1H-1,2,4-triazol-1-yl)anthracen-10-yl]-1H-1,2,4-triazole (tatrz) in a molar ratio of 1: 1 is the best response ratio.
