摘要

以1，8-萘酐、N，N-二甲基乙醇胺、三乙烯四胺为原料，通过酰亚胺化、缩合等反应，合成一种萘酰亚胺荧光探针，并通过核磁氢谱、红外光谱结构表征，测定了探针在乙醇与水的混合溶液中的荧光光谱。考察了金属离子浓度等因素的影响，对其配位机理进行了研究。结果显示，目标产物在乙醇-水溶液中对Fe

表现出了专属选择性识别性能，在（1.87~6.53）10

-6

浓度范围内，探针荧光强度与Fe

浓度有很好的线性关系，线性相关系数

=0.995 3，检出限为405.1 ng/mL。

Abstract

A naphthalimide fluorescent probe was synthesized using 1

8-naphthalene anhydride

N-dimethylethanolamine and triethylene tetramine as raw materials and characterized by

H NMR and IR spectra. The fluorescence spectra of the fluorescent probe in ethanol/water mixed solution were measured. The influence of metal ion concentration on the fluorescence intensity was investigated

and the proposed mechanism between the probe molecule and Fe

was studied. The results demonstrate that the target product shows the exclusive recognition performance to Fe

in ethanol/water mixed solution. When the concentration of Fe

is in the range of (1.87~6.53)10

-6

g/mL

the fluorescence intensity of the probe has good linearly relationship with the concentration of Fe

. The linear correlation coefficient

is 0.995 3

and the detection limit is 405.1 ng/mL.
