【摘要】 通过2-甲基-5-联苯基噁唑分别与苯甲醛、取代苯甲醛和呋喃甲醛缩合,合成了十五种2-(2’-取代乙烯基)-5-联苯基噁唑。测定了它们的熔点、红外光谱、核磁共振谱、紫外光谱、荧光光谱、荧光量子产率和激光转换效率.并借助红外谱图、核磁谱图对化合物的结构进行了分析.更多还原

【Abstract】 Fifteen of the 2-(2’-substituted vinyl)-5-biphenylyl oxazoles were synthesized respectively by condensation of the corresponding 2-methyl-5-biphenylyl oxazole with benzaldehyde,substituted benzaldehydes or furfural in tha presence of alkali or acid. Their m. p., infrared spectra, NMR spectra, λman of UV spectra and fluorescence spectra, fluorescence quantum yield as well as laser properties of the compounds are listed in tables.更多还原
