A series of dendritic 8-hydroxyquinoline (8-HQ) and 5-dialkyl(aryl)aminomethyl-8-HQ derivatives were synthesized and their fluoroionophoric properties toward representative alkali, alkaline earth, group IIIA and transition metal ions were investigated. Among the selected ions, Zn(II) enhanced the fluorescence of N-di-(methoxycarbonylethyl)aminoethyl-3-[4-(8-hydroxyquinolin-5-ylmethyl)piperazin-1-yl]-propanoic amide] (7) by 31-fold, while Al(III) caused enhancement to some extent. The absence of any significant fluorescence enhancement by the other ions examined renders 7a highly useful Zn(II)-selective fluorescent sensor.

合成了一系列树枝状8-羟基喹啉（8-HQ）和5-二烷基（芳基）氨基甲基-8-HQ衍生物，并研究了它们对代表性碱金属、碱土金属、IIIA族和过渡金属离子的氟离子载体性能。在所选择的离子中，Zn（II）使N-二-（甲氧基羰基乙基）氨基乙基-3-[4-（8-羟基喹啉-5-基甲基）哌嗪-1-基]-丙酰胺（7）的荧光增强了31倍，而Al（III）在一定程度上也引起了荧光增强。所检测的其他离子均未引起任何显著的荧光增强，这使得7a成为一种非常有用的Zn（II）选择性荧光传感器。
