Embodiment 1

[0017] Weigh 5-aminoisophthalic acid (25mmol), add concentrated HCl and H 2 O each 8mL, heated until all solids dissolved, poured into H2O cooled to 0°C 2 O (400mL) for use; weigh NaNO 2 (25mmol), add H 2 O (5mL), after cooling to 0°C, slowly drop into the above-mentioned 5-aminoisophthalic acid solution and stir rapidly for about 30 minutes, then add NaN 3 Aqueous solution (30mmol NaN 3 Dissolve in 10mLH 2 O), a white precipitate was generated, filtered by suction, washed with distilled water and dried to obtain the intermediate product 5-azidophthalic acid. Weigh the intermediate product 5-azidophthalic acid (10mmol), add benzene acetylene (1.1mL), DMSO (40mL) and H 2 O (10mL), after stirring the reaction for 10 minutes, add vitamin C sodium (1mmol) and CuSO 4 (0.1 mmol), heated to 65°C and stirred for 24 hours, cooled naturally in an ice bath, and crystals grew. Through X-ray single crystal diffraction analysis, it is determined that the crystal is 1-(3,5-benzenedica...

Abstract

The invention provides a blue fluorescent luminescent organic compound and a method for synthesizing the same. The invention relates to synthesis, crystal growth and an application of a yellow fluorescent luminescent organic compound. The molecular formula of the compound is C16H11N3O4, and the space group of the compound is C2 / c. The unit cell parameters of the compound are as follows: a is equal to 7.2735(9); b is equal to 17.2359(18); c is equal to 23.744(3); alpha is equal to 90 degrees; beta is equal to 93.235(2) degrees; gamma is equal to 90 degrees; Z is equal to 8, and the unit cell volume V of the compound is equal to 2972.0(6)<3>. The compound is prepared by adopting three-step reaction, namely diazo reaction, azide substitution and cyclic addition. The compound emits strong blue fluorescence nearby 430 nm. 1-(3, 5-phthalic acid)-4-phenyl-1, 2, 3-triazole can become a novel fluorescent luminescent material and can be used for manufacturing fluorescent luminescent devices.

Description

technical field [0001] The invention relates to the synthesis, crystal growth and application of a yellow fluorescent light-emitting organic compound. Background technique [0002] 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. Relatively speaking, the research on fluorescence emission is more in-depth and applied more extensive. Organic compounds with strong fluorescent light-emitting ability have very important potential application value, and can be developed as new functional materials, such as luminescent dyes, laser dyes, sensitizing dyes, fluorescent probes, etc. The fluorescence behavior of organic compounds, including the fluorescence emission intensity (fluorescence quantum yield) and the position of the emission peak wavelength, is not only related to the m...
