Embodiment 1

[0024] The molar ratio of 4,4'-diaminodiphenyl sulfide to bisformylhydrazide is 1:2.

[0025] Add 4,4'-diaminodiphenylsulfide (1 mmol) and bisformylhydrazide (2 mmol) respectively into a 50 mL three-neck round bottom flask equipped with a magnet, reflux condenser and thermometer, and start stirring at 160 °C, react for 12 hours. After the reaction was completed, the reaction solution was cooled to room temperature, and a large amount of precipitate was precipitated, which was recrystallized with water and ethanol, and the yield was 86%. Elemental Analysis C 16 h 12 N 6 Theoretical values ​​for S: C, 59.98; H, 3.78; N, 26.23. Experimental values: C, 60.09; H, 3.74; N, 26.13.

Embodiment 2

[0027] The luminescent agent has fluorescent properties; the specific method steps are as follows:

[0028] Scan the excitation wavelength and emission wavelength of the compound (Example 1) with a spectrofluorometer to select and determine the optimum wavelength.

[0029] Conclusion: The excitation and emission wavelengths of this compound are 375 nm and 550 nm, respectively.

Abstract

The invention discloses a thioether bitriazole compound as well as a preparation method and application of the thioether bitriazole compound, and particularly discloses a bi(4-(4H-1, 2, 4-triazole-4-yl)phenyl)thioether compound and a preparation method of the bi(4-(4H-1, 2, 4-triazole-4-yl)phenyl)thioether compound. The organic compound is prepared by using a one-pot method, namely heating 4, 4'-biamino diphenyl sulfide and diformylhydrazine. The preparation method disclosed by the invention has the characteristics of simple technological operation, low production cost and little environmental pollution and is suitable for large-scale industrial production. The bi(4-(4H-1, 2, 4-triazole-4-yl)phenyl)thioether compound prepared by using the preparation method can be applied to the aspects of photoelectric materials and luminescent agents.

Description

[0001] The invention is supported by the General Project of National Natural Science Foundation of China (21471113), the project funding of Tianjin Municipal Education Commission (20140506) and the funding of Tianjin Higher Education Innovation Team Training Program (TD12-5038). technical field [0002] The invention belongs to the technical field of organic synthesis, and relates to bis(4-(4H-1,2,4-triazol-4-yl)phenyl)sulfide compound and its preparation method, bis(4-(4H-1, Application of 2,4-triazol-4-yl)phenyl)sulfide in luminescent agent. Background technique [0003] 1,2,4-triazole and its derivatives have the coordination characteristics of pyrazole and imidazole, and are bridging ligands with strong coordination ability. A large number of mononuclear, multinuclear and multidimensional compounds have been synthesized and characterized . These ligands can form N1, N2-bridge mode by coordinating the nitrogen atom on the 1,2 position with the metal ion, and the unsubs...
