本文将2—联苯基—5—苯基噁唑及其5一对位取代苯基衍生物同2—苯基—5—联苯基噁唑及其2—对位取代苯基衍生物在紫外吸收光谱和荧光发射光谱的性质上做了比较,简单讨论了光谱性质和化合物分子结构之间的关系,也从理论上简单说明了一些光谱现象。 In this paper, 2-biphenyl-5-phenyloxazole and its 5-para-substituted phenyl derivatives were reacted with 2-phenyl-5-biphenyloxazole and their 2-para-substituted phenyl derivatives UV absorption spectra and fluorescence emission spectra are compared in nature, a brief discussion of the relationship between the spectral properties and the molecular structure of compounds, but also a simple description of some of the spectroscopic phenomena in theory.
