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.
- benzoxazole,
