摘　　要：合成了3个3,5-二（2’-芳基-1’,3’,4’-噁二唑基）吡啶化合物,用1H-NMR、FT-IR、MS对其结构进行了表征。研究了它们的UV-Vis吸收光谱、荧光光谱和电化学性能,吸收光谱表明：在270~273nm出现最大吸收峰;荧光光谱表明：目标化合物的DMF溶液发射强的紫色荧光,在334~356nm出现最大发射峰;固体发射强的紫蓝色荧光,在376~402nm出现最大发射峰。电子亲和势为2.72~3.11eV,离子势为6.28~6.70eV,说明目标化合物的电子传输性能良好（PBD：EA=2.82eV）。Three novel compounds of 3,5-bis（2＇-phenyl-l＇,3＇ ,4＇-oxadiazole） pyridine have been synthesized. The structures of these compounds were confirmed by 1H NMR,FT-IR and MS. their UV-Vis spectroscopy, as well as fluo- rescent spectroscopy and electrochemical properties were studied. UV-Vis spectroscopy results showed that the maximum absorptive wavdength of target compounds were detected at 270~273nm, Fluorescent spectroscopy results showed that they were found to emit strong purple fluorescence in DMF solution, the emissive maximum wavelength of target corn pounds were from 334 to 356nm; The solid of target compounds were found to emit strong purp].e and h!.ue fluorescence, the emissive maximum wavelength of target compounds were from 376nm to 402nm. The target compounds kept high affinity energy （2.72-3. lleV） and ionic potential （6.28-6.70eV）, which indicated that they were potentially better mate- rials as the electron transfer （PBD2 EA=2, 82eV）.
