Abstract

A poly(amine ester) dendrimer with naphthyl units (G1N6) has been synthesized as a fluorescent chemosensor for metal ions. We investigated the metal-ion recognition of G1N6 by adding each of Ag(+), Al(3+), Ba(2+), Ca(2+), Cd(2+), Co(2+), Cu(2+), Fe(3+), Mg(2+), Ni(2+), and Zn(2+) in acetonitrile solution. Large changes were observed in the fluorescence spectra of G1N6 upon the addition of Al(3+), Cu(2+), and Zn(2+).

摘要

一种带有萘基单元的聚（胺酯）树枝状大分子（G1N6）已被合成作为金属离子的荧光化学传感器。我们通过在乙腈溶液中分别加入Ag(+)、Al(3+)、Ba(2+)、Ca(2+)、Cd(2+)、Co(2+)、Cu(2+)、Fe(3+)、Mg(2+)、Ni(2+)和Zn(2+)来研究G1N6对金属离子的识别。加入Al(3+)、Cu(2+)和Zn(2+)后，G1N6的荧光光谱发生了很大变化。
