Synthesis and application of blue-fluorescence luminous zinc metal complex

Abstract

The invention relates to the synthesis and the application of tetrazole-5-butyric acid zinc metal complex as a blue-fluorescence luminous material. An in-situ hydrothermal synthetic method is adopted, a mol ratio of reactants of ZnCl2, NCCH2CH2CH(COOC2H5)2, NaN3 and MnCl2 is 1:1:2:1, a certain amount of NaOH is added, water is adopted as a solvent, the solvent is heated to 140-160DEG C by hydro-thermal reaction, remains constant temperature for 50-70hours and then is cooled to room temperature, and the tetrazole-5-butyric acid zinc metal complex can be prepared. The tetrazole-5-butyric acid zinc metal complex emits stronger blue fluorescence near 412nm, can become a novel fluorescence luminous material and can be used for preparing a fluorescence luminous device.

Description

technical field

[0001] The invention relates to a blue fluorescent luminescent material zinc tetrazolium-5-butyrate metal complex (molecular formula: C 5 h 6 N 4 o 2 Zn) synthesis and application. Background technique

[0002] Due to the diversity and tunability of their structures, the value and application of metal-organic complexes have attracted increasing attention. They play an important role in functional materials such as luminescent materials, magnetic materials, catalytic materials, magneto-optical storage materials, and hydrogen storage materials. It can be developed as a new functional material. At present, scientists have conducted in-depth research on the luminescent properties of metal complexes. Substance molecules and atoms are excited by absorbing light radiation, and then emit light with the same wavelength or longer than the absorption wavelength, which is called photoluminescence, and the most common ones are fluorescence and phosphorescence.

Examples

Embodiment Construction

[0010] 1. Preparation of compounds

[0011] Weigh ZnCl 2 (0.3mmol), NCCH 2 CH 2 CH(COOC 2 h 5 ) 2 (0.3mmol), NaN 3 (0.6mmol) and MnCl 2 (0.3mmol), and add a certain amount of NaOH (0.7-0.9mmol), add 5mL of distilled water, put into a closed 25mL reaction kettle, heat up to 140-160°C, keep the temperature for 50-70 hours, then cool down to room temperature, crystals can be obtained. After X-ray single crystal diffraction analysis, it was determined that the crystal was C 5 h 6 N 4 o 2 Zn.

[0012] 2. Fluorescence test

[0013] The prepared crystals were ground uniformly to obtain solid powders, and the fluorescence emission performance test was carried out on an Edinburgh EI920 fluorescence spectrometer. The results showed that strong blue fluorescence was emitted near 412nm.
