摘　　要：以自制的N,N-二酰基肼在SOCl2作用下脱水环化。合成了6个1,4-二(2′-芳基-1′,3′,4′-噁二唑基)-1,3-丁二烯类化合物,通过1H NMR、FT-IR和MS对其结构进行表征。研究了它们的紫外-可见吸收光谱和荧光光谱。结果表明:在336～350nm出现最大吸收,发射强的蓝色荧光,最大发射峰出现在390～477nm,是一类稳定的蓝光发光材料。Six novel 1,4-bis （ 2＇-phenyl-1＇, 3＇, 4＇-oxadiazole ）- 1,3-butadiene compounds were synthesized via eyclization of SO- Cl2 with N, N＇-diacylhydrazines. The structures of these compounds were characterized by ^1HNMR, FT-IR and MS. The UV- Vis spectroscopy and fluorescence spectroscopy of the said compotmds were studied, the results showed that the maximum absorptive wavelength was detected at 336 - 350 nm, and the maximum emissive wavelength of polyamides ranged from 390 - 477 nm. The test results showed that the target compounds were a kind of stable blue luminescent materials.
