摘要：

设计合成了喹啉取代的氟硼二吡咯荧光探针(BHQ),并用核磁共振波谱仪(NMR)和高分辨质谱仪(HRMS)等技术手段对合成的化合物进行了表征。结果表明,在水溶液中,探针BHQ在Fe³⁺存在下具有良好的荧光增强识别效果,对 Fe³⁺ 具有响应快、较好的灵敏度和选择性特点,而其它金属离子的存在不干扰 Fe³⁺ 的检测。探针BHQ与Fe³⁺以摩尔比1:1的方式进行配位。该探针在Fe³⁺的检测方面具有潜在的应用价值。

Abstract:

A quinoline substituted boron dipyrromethene(BODIPY) based probe(BHQ) was synthesized and characterized by nuclear magnetic resonance spectroscopy(NMR) and high resolution mass spectrometer(HRMS). The probe shows significant enhancement of fluorescence intensity in the presence of Fe³⁺ in aqueous solution. The probe exhibits fast response, high sensitivity and high selectivity toward Fe³⁺, while other common metal ions do not show significant interference. The binding between the probe and Fe³⁺ has been found to be in 1:1 mole ratio based on Job's plot. This result suggests that the probe BHQ has potential application in the determination of Fe³⁺ ions.

Key words: boron dipyrromethene, quinoline derivatives, fluorescent probe, ion sensing, ferric ion
