A series of 5-dialkyl(aryl)aminomethyl-8-hydroxyquinoline dansylates were synthesized and their fluoroionophoric properties toward representative alkali ions, alkaline earth ions and transition metal ions were investigated. Among the selected ions, Fe3+ caused considerable quenching of the fluorescence, while Cr3+ caused quenching to some extent. The absence of any significant fluorescence quenching effects of the other ions examined, especially Fe2+, renders these compounds highly useful Fe3+-selective fluorescent sensors.
合成了一系列 5-二烷基(芳基)氨基甲基-8-羟基喹啉丹酰化合物,并研究了它们对代表性碱离子、碱土离子和过渡金属离子的荧光亲和性。在所选离子中,Fe3+ 会导致大量荧光淬灭,而 Cr3+ 则会在一定程度上导致荧光淬灭。所研究的其他离子,尤其是 Fe2+,没有明显的荧光淬灭效应,因此这些化合物是非常有用的 Fe3+ 选择性荧光传感器。
