摘　　要：以5-氨基-1,3-苯二甲酸和对甲氧基苯甲酰肼为原料,经过重氮化、酰氯化、肼解、脱水关环反应,合成了一种有机电致磷光材料的重要中间体:3,5-二[5-′(4″-甲氧基苯基)-1,′3,′4′-噁二唑-2′-基]-溴苯,关环反应产率为53.2%.探讨了反应条件对合成反应的影响,研究了该化合物的紫外吸收光谱和荧光光谱特性.结果表明:该化合物氯仿溶液的最大紫外吸收波长为307 nm,最大荧光发射波长为376 nm.An important intermediate for making electroluminescent materials, namely, 5-bromo-1,3-Bis[ （2-phenyl）-5- （4′-methoxyphenyl）]-1, 3, 4-oxadiazole, was synthesized by using 5-amino-1, 3-benzenedicarboxylic acid and 4-methoxy benzoyl hydrazine as raw materials and undergoing a serial of reactions, such as diazotization, acylchloride, diarylhydrazide and dehydration. The yield of the dehydrated reaction was 53.2%. Its structure was characterized with IR, ^1H NNR. The influences of reactive conditions on the synthesis, UV spectrum and the fluorescence properties were investigated. The result shows that the CH3Cl solution of this compound had a maximum UV absorption wavelength of 307 nm and a peak fluorescent wavelength of 376 nm.
