摘要
通过酰氯化、二酰肼化和脱水关环反应,合成1,4-二[5-(4-羟基苯基)-1,3,4-噁二唑-2-基]苯,关环反应产率达到78.9%,产物结构经核磁氢谱得到了表征.探讨了反应条件对合成噁二唑衍生物的影响,研究了它们的紫外吸收和光致发光性能.研究结果表明:目标化合物具有强烈的紫外吸收和光致发光性能,其最大紫外吸收波长在286.8nm,最大荧光发射波长在375nm.作为电致磷光中间体的对称2,5-二苯基-1,3,4-噁二唑中引入羟基对,进一步连接其它功能基合成新型的有机环金属电致磷光材料具有重要的意义.
1,4 - dis [ 5 - （4 - hydroxylphenyl） - 1,3,4 - oxadizol -2 - yl）benzene was prepared by dehydration of diarylhydrazide. The influence of reaction condition on synthesis was investigated. A yield of 78.9% was obtained in dehydration reaction, and the structures was characterized by 1HNMR. The influence of reaction condition on synthesis was investigated. The UV absorption and photoluminescence （PL） properties of this compound was studied too. The results showed that the maximum UV absorption wavelengths of the hydroxyldiphenyl - 1,3,4 - oxadiazole was in the range of 286.8 nm and the maximum photoluminescent wavelengths was located at 375 nm. As eleetrophosphorescent interediates, It is significant to further synthesize novel organic electrophosphorescent materials becase of the hydroxyl .
