摘要

本文报道了一种新的Al3+荧光探针M1[二甲基3,3 '-((2-丁基- 1,3 -二氧基- 2,3 -二氢- 1h -苯并[de]异喹啉-6-基)氨基)乙基)氮杂二基)二丙酸]。其紫外可见吸收光谱和荧光光谱具有显著的光学特性。考察了反应温度、pH、反应时间等最佳条件。该体系对其他16种金属离子具有良好的抗干扰能力。M1与Al3+浓度呈良好的线性关系(1 × 10-6 ~ 15 × 10-6 mol/L)。检出限为7.55 × 10-8 mol/L。具有良好的抗干扰性。它对干扰有极好的抵抗力。M1探针与Al3+的络合比为1:1。并对其结合机理进行了推测。我们首次将所构建的荧光系统应用于中草药中Al3+的测定及活细胞荧光成像。

Synthesis and Determination of Al3+ in Chinese Herbs from Heilongjiang Province by Fluorescent Probe of Naphthalimide

We reported a new naphthalimide fluorescence probe M1[dimethyl 3, 3'-((2-((2-butyl-1, 3-dioxo-2, 3-dihydro-1H-benzo[de] isoquinolin-6-yl) amino) ethyl) azanediyl) dipropionate] with Al3+ fluorescence system. Its UV-visible absorption spectrum and fluorescence spectrum showed remarkable optical characteristics. The optimal experimental conditions, including reaction temperature, pH, and reaction time were investigated. This system possessed a good anti-interference ability toward the other 16 metal ions. The M1 shows good linearity with Al3+ concentration (1 × 10-6 ~ 15 × 10-6 mol/L). The LOD (Limit of Detection) was 7.55 × 10-8 mol/L. It has good resistance to interference. It was excellently resistant to interferences. The complexation ratio between the M1 probe and Al3+ is 1:1. Furthermore, the binding mechanism was conjectured. We applied the constructed fluorescence system for the first time to the determination of Al3+ in Chinese herbal medicines, and fluorescence imaging in living cells.
