摘　　要：提出了一种新的合成1,3,4-噁二唑化合物的方法,并通过Wittig反应将其与1,3,5-三芳基-2-吡唑啉相连合成了6种新的三芳基吡唑啉噁二唑类化合物.用红外光谱、质谱、核磁共振谱和元素分析对合成化合物进行了结构表征.用荧光光谱仪对它们的荧光性能进行了测试,测试结果表明目标产物具有良好的荧光性,其荧光发射波长均在437～511nm范围内,荧光量子产率最大可达0.36.A new method of synthesizing 1,3,4-oxadiazole compound was described. The synthesized 1,3,4-oxadiazole compounds were connected with 1,3,5-triaryl-2-pyrazoline through Wittig reaction, and six new triaryl pyrazoline oxadiazole compounds were synthesized. Their structures were characterized by IR, MS, 1H NMR techniques and elemental analysis. The fluorescence properties were measured by fluorometry, and the test results showed that the target compounds have good fluorescence and λem ranged from 437 to 511 nm, fluorescence quantum yield up to 0.36.
