2-萘基-5-取代苯并唑的合成、紫外光谱和萤光光谱

Synthesis,Ultraviolet and Fluorescence Spectra of 2(1-or 2 Naphthyl)-5-Substituted Benzoxazoles

在研究有机化合物的结构与光性能间关系的过程中,我们又通过4-取代-2-氨基酚或其盐酸盐分别与α-萘甲酸和β-萘甲酸缩合,制得了十种2-(α-萘基)-5-取代苯并唑(Ⅰ)和十种2-(β-萘基)-5-取代苯并唑(Ⅱ),测定了这些化合物的熔点,紫外吸收光谱和萤光发射光谱.

Ten 2-(1-naphthyl)-5-substituted benzoxazoles as well as ten 2-(2-naphthyl)-5-substituted benzoxazoles are synthesized and theirλ_(max)of UV spectra and fluorescence spectra are reported.
