摘要

荧光分子探针具有高选择性、灵敏度，同时成本低廉，操作简便，近年来备受关注。本文通过重氮偶合法合成了2, 4-二氨基-2’-羧基-偶氮苯(L1)，并用核磁共振(NMR)、红外光谱(IR)对化合物进行表征。光谱分析结果表明，相对于单独L1配体，L1与Zn(II)离子的紫外吸收光谱发生变化，在356 nm处出现等位点。同时，当L1与Zn(II)金属盐溶液作用时，L1由黄色变为橙色，在484 nm处观察到明显的荧光增强(λex = 330 nm)，为蓝绿色荧光。此外，L1对市售的葡萄糖酸锌营养液存在感应作用，使得L1可作为锌补充剂中的Zn(II)离子的测试材料。

Abstract:

The design of fluorescent probe to detect Zn(II) ion high sensitively and operational simply has been attracted much attention recently. In this study, 2, 4-diamino-2'-carboxyl azobenzene (L1) was synthesized and characterized by NMR, IR spectra. The UV absorption spectra of L1 with Zn(II) ion changed with an isosbestic point at 356 nm. When L1 reacted with ZnSO₄, the distinct colour of L1 changed from yellow to orange. In the solution of L1 and ZnSO₄, a marked enhanced fluorescene enhancement was observed at 484 nm (λex = 330 nm) and emitted cyan fluorescence under UV light. Furthermore, L1 reacted with zinc gluconate solution, which makes L1 can be serves as the applied material to test Zn(II) ion in zinc supplement.

Key words: azo compound zinc gluconate UV Spectroscopy fluorescence
