摘要/Abstract

摘要： 合成了2-联苯基-5-苯基噁唑和13种5-对位取代苯基衍生物,测定了它们的熔点,红外紫外吸收光谱,萤光发射光谱,萤光量子产率(φ_i)和激光转换效率(η_i)。

Abstract: 2-(p-Biphenyl)-5-phenyl-oxazole and thirteen 5-substituted phenyl-derivatives are synthesized. Among them, eleven are new compounds. The m. p. λmax of IR, UVabsorption spectra and fluorescence emission spectra, as well as fluorescence quantum efficiency and laser properties of the compounds are given in tables. It is found that eleven of the titled compounds are better than 2,5-diphenyl oxazole (PPO) in using as laser dye in near UVregion.Abrief discussion on the relation between the substituent effects and spectral properties of the compounds is given.
