| 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. |
