In order to find a highly sensitive fluorophore, 3-azolyl-7-diethylaminocoumarin derivatives were synthesized. Both the absorption and fluorescence maxima of the coumarin-thiazole compounds showed red shifts with increases of the molar absorptivities and fluorescence intensities, in comparison with those of the corresponding coumarin-oxazole compounds. Among them, 3-(5-ethoxycarbonyl-1, 3-thiazol-2-yl)-7-diethylamino-2H-chromen-2-one (3e) was one of the most promising candidates as a fluorophore accessible for analytical purposes in the fields of analytical and biological chemistry.
为了寻找高度敏感的荧光探针,合成了3-杂唑基-7-二乙氨基香豆素衍生物。这些香豆素-噻唑化合物的吸收和荧光最大值均表现出红移,相比于相应的香豆素-噁唑化合物,其摩尔吸光度和荧光强度均有所增加。其中,3-(5-乙氧基羧基-1, 3-噻唑-2-基)-7-二乙氨基-2H-香豆素-2-酮(3e)是作为分析用途的荧光探针中最有前途的候选者之一,适用于分析化学和生物化学领域。
