Abstract: E,E-1,4-bis[2', 2"-(benzoxazolylethenyl)]benzene and thirteen of its substituted derivatives were synthesized.Their m.p., ultraviolet-visible absorption spectra and fluorescence emission spectra, fluorescence quantum yields as well as laser properties were determined.Configurations of these compounds were identified by IRand 1H NMR.The relationship between optical property and structure was discussed.It was found that E,E-1, 4-bis[2', 2"-(benzoxazolylethenyl)]benzeneand its substituted derivatives possess well photochemical stability and higher laser conversion efficiency than Coumarine-47.The synthesis of 2-methylbenzoxazole and substituted derivatives were also reported.
Key words: Benzoxazole, UV spectrum, FL spectrum, Laser dye
