合成了两种新颖的三乙二醇二香豆素-3-羧酸酯,并通过元素分析,(1)1 H NMR,FT-IR和UV-vis吸收光谱进行了表征。讨论了在PMMA中掺杂的三乙二醇二苯并[5,6]香豆素-3-羧酸酯的光致发光行为。这些化合物在紫外光激发下显示出强烈的蓝色发射。与香豆素-3-三乙二醇二酯相比,苯并[5,6]香豆素-3-三乙二醇二酯的吸收和发射光谱由于苯部分的较大共轭而发生了红移。这些衍生物具有探索有机电致发光材料的潜力。

extensively due to its rapid and low detection limit ability. Sodium and potassium differentiation is significant in diagnosis of many medical conditions. For this, we designed coumarin dimers as flexible fluorescent probes using ethylene glycol units for differentiation of sodium and potassium. To our best knowledge, use of these easy-to-synthesize coumarin dimers linked through ethylene glycol units are
