摘要: 本文合成了二十六种2-苯基和2-取代苯基-5-(4'-联苯基)噁二唑化合物,测定了这些化合物的熔点、紫外吸收光谱、荧光发射光谱、荧光量子产率和激光转换效率。其中十七种化合物在近紫外区有较高的激光转换效率。

Abstract: 2-Phenyl- and twenty five of 2-(substituted phenyl)-5-(4'-biphenyl-yl) oxadiazoles were synthesized. The. m.p., λmax of UVabsorption spectra and fluorescence emission spectra, fluorescence quantum yield as well as laser properties of the compounds are given in tables. It is found that seventeen of the compounds give higher conversion efficiency than PPOin near UVregion.
