Two novel stilbene derivatives containing 1,3,4-oxadiazole moiety were synthesized and characterized by elemental analyses, (1)H NMR, MS. The photophysical processes of the title compounds were investigated by UV-vis absorption and fluorescence emission spectra in different solutions. The fluorescence quantum yield (Phi) of 1a and 1b in THF is 0.65 and 0.69, respectively. The influence of the solution on the fluorescence intensities was also discussed. Under ultraviolet light excitation, the two compounds exhibit strong blue fluorescence emission. They may serve as potential applications in organic electroluminescent materials.
合成了两种含1,3,4-恶二唑部分的新型芪衍生物，并通过元素分析、¹H NMR、质谱对其进行了表征。通过在不同溶液中的紫外可见吸收光谱和荧光发射光谱研究了标题化合物的光物理过程。1a和1b在四氢呋喃中的荧光量子产率（Φ）分别为0.65和0.69。还讨论了溶液对荧光强度的影响。在紫外光激发下，这两种化合物呈现出强烈的蓝色荧光发射。它们可能在有机电致发光材料中具有潜在应用。
