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．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.
