摘要： 合成了7种2-(4-联苯基)苯并 唑衍生物,其中5种为未知物。经元素分析、IR、UV、1HNMR和MS表征,并测定了上述化合物的荧光发射光谱、荧光量子产率和激光转换效率,结果发现5,7-二异丙基-2-(4-联苯基)苯并 唑的激光转换效率高,具有应用价值。

关键词: 苯并　唑, 激光转换效率, 荧光发射光谱

Abstract: Seven derivatives of 2-(4-biphenyl)benzoxazole were synthesized. Five of them are new compounds. They were identified by elemental analysis, IR, UV, MS and 1H NMR. Their fluorescence emission spectra. fluorescence quantum yields and laser conversion efficiencies were determined. The results showed that 5, 7-diisopropyl-2-(4-biphenyl)benzoxazole has high laser conversion efficiency and wide tuning range. It may be a valuable laser dye.

Key words: benzoxazole, laser conversion efficiency, fluorescence emission spectrum
