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 3,5-bis (2’-aryl-1 ’, 3’, 4’-oxadiazolyl) pyridine compounds were synthesized and their structures were characterized by 1H-NMR, FT-IR and MS. Their UV-Vis absorption spectra, fluorescence spectra and electrochemical properties were studied. The absorption spectra showed that the maximum absorption peak appeared at 270 ~ 273nm. The fluorescence spectra showed that the target compound’s DMF solution emitted strong purple fluorescence and appeared at 334 ~ 356nm The maximum emission peak; solid emission strong purple-blue fluorescence, the maximum emission peak at 376 ~ 402nm. The electron affinity was 2.72 ~ 3.11 eV and the ion potential was 6.28 ~ 6.70 eV, indicating that the electron transport properties of the target compound were good (PBD: EA = 2.82 eV).
