Abstract

Abstract: A series of dendritic 8-hydroxyquinoline (8-HQ) and 5-dialkyl (aryl) amino-methyl-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 ...
