摘　　要：以4-吡唑苯甲醛和2-甲基喹啉为原料,通过简单高效的方法设计合成了一种喹啉衍生物新型荧光探针。利用紫外可见吸收光谱和荧光光谱研究了探针对HSO-3的识别行为。研究结果表明,探针对HSO-3的响应明显强于其他阴离子,且不受其他阴离子的干扰,该荧光探针可用于检测亚硫酸氢根(HSO-3),探针对HSO-3的检测限为11.80μM。A new fluorescent probe based on quinoline derivatives for detecting HSO-3with a simple and efficient method using 4-pyrazolbenzaldehyde and 2-methylquinoline has been designed and synthesized.The recognition of HSO-3 by the probe has been investigated by using UV-vis absorption and fluorescence spectra.The experiment demonstrates that the probe displays high selectivity and capability of sensing HSO-3without being interfered by other anions as well as a low detection limit(11.80μM).
