摘要

合成了含有喹啉功能团的锌离子荧光探针

N'-(喹啉-2-亚甲基)-3-(-喹啉-2-亚甲基胺)苯甲酰肼(QQB)

该探针与Zn

结合后荧光发射光谱由40nm红移至10nm

且荧光强度增强

具有较高的检测灵敏度.生物体内含量较高的金属阳离子K

、Na

、Mg

、Ca

以及微量金属离子Mn

、Co

、Ni

等对QQB-Zn

的荧光强度无显著影响

表明QQB对锌离子具有较高的选择性.光谱滴定和ESI-MS谱表明QQB与Zn

以1:1的化学计量比形成配合物.

Abstract

(E)-N'-(quinolin-2-ylmethylene)-3-[(E)-quinolin-2-ylmethyleneamino]-benzohydrazide(QQB)

as a chelating fluorophore

can detect Zn

selectively by shifting emission peak from 405 nm to 510 nm upon Zn

addition.Zinc binding not only makes the emission band red-shifts

but also enhances the fluorescence intensity.The probe is highly selective for Zn

over biologically relevant alkali metals

alkaline earth metals and the first row transition metals such as Mn

and Ni

.Spectrophotometric titration and ESI-MS spectra indicate the formation of a 1:1 complex of Zn

with QQB.
