Synthesis and spectral characteristics of 2,6-bis(2′-phenyl-1′,3′,4′-oxadiazole) pyridine

合成了3个2，6-二（2’-芳基-1，3’，4＇-噁二唑基）吡啶化合物，用1^H 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。紫外-可见吸收光谱表明：目标化合物在278-309nm出现最大吸收峰；荧光光谱表明：目标化合物在DMF溶液中发射强的紫色荧光，在364—398nm出现最大发射峰；固体发射强的紫蓝色荧光，在376-414nm出现最大发射峰。

Three novel compounds of 2,6- bis （ 2＇-phenyl- 1＇, 3＇, 4＇-oxadiazole） pyridine have been synthesized. The structures of these compounds were confirmed by 1^HNMR, FT-IR and MS. Their UV-Vis spectroscopy data as well as fluorescent spectroscopy data were studied. The UV-Vis spectroscopic results showed that the maximum absorptive wavelength of target compounds were detected at 278 - 309 nm, Fluorescent spectroscopy results showed that they were found to emit strong purple fluorescence in DMF solution, and the emissive maximum wavelength of target compounds were from 364 nm to 398 nm;The solid state target compounds were found to be emitting strong purple and blue fluorescence, and the emissive maximum wavelengths of target compounds were from 376 nm to 414 nm.
