摘要： 通过4-RC6H4CHO与2-(4-甲基苯基)-5-(4-联苯基)口恶唑(R=H,Me,Et,i-Pr,i-Bu,Ph,OMe,F,Cl,Br)在碱催化下的缩合反应合成了10个新的反式-2-{4-[2-(4-取代苯基)乙烯基]苯基}-5-(4-联苯基)口恶唑类化合物,经元素分析、IR、UV及MS确定了它们的结构。并测定了荧光发射光谱、荧光量子产率和激光转换效率。

Abstract: Ten trans 2-{4-[2-(4-R-phenyl)ethenyl]phenyl}-5-(4 biphenyl)oxazoles(R=H, Me, Et, i-Pr, t-Bu, Ph, OMe, F, Cl, Br)were synthesized. They were identified by elemental analysis、 IR、 UV and MS. Their FL spectra, fluorescence quantum yields and laser conversion efficiencies are reported and discussed.

Key words: diaryloxazole, synthesis, electronic spectrum, laser conversion efficiency
