    摘要: 本研究以間苯二甲酸及5-硝基間苯二甲酸為原料,製備双-1,3,4- This research is with isophthalic acid and 5-nitroisophthalic acid, as raw materials. Prepare bis-1,3,4-oxadiazole series chemical compounds. Can all win the purpose thing in accordance with the method step of papers. Among them every bis-1,3,4-oxadiazole series chemical compounds all shows the absorption peak of 1724 cm-1 on IR spectrum. Unknown it where characteristic of part absorb and how analyze for chemical compound. Every bis-1,3,4-oxadiazole series chemical compounds have nitro group all simple antithetical couplet when NH2NH2/Pd-C method is reduced for the amine group. This kind of amine group can also condensation reaction with the Cyanuric chloride. And become the water soluble chemical compounds. 5-nitroisophthalic acid can have azobenzene while reducing in the zinc powder-NaOH's aqueous solution, and the rate is 90%. This azobenzene has four formic acid. Can all esterify, Hydrazine hydrate and benzoyl chloride. Cyclodehydration is used in phosphorus oxychloride to be azobenzene with four pieces of 1,3,4-oxadiazole. The above-mentioned chemical compounds formate the purpose and increase its fluorescence intensity or the fluorescence of different wavelength emerges because of increase of 1,3,4-oxadiazole in the income result. Cause because of azobenzene(-N=N-) of the result. Fail to increase its fluorescence intensity and wavelength.
