【摘要】 一种具有腙类结构的化学传感器N4被设计合成出来,用于水溶液中氟离子的比色响应,并具有高选择性和高灵敏度。加入氟离子后,裸眼可以观察到探针溶液颜色从黄色变为浅紫色;加入其它阴离子后溶液颜色无明显变化,同时对氟离子的识别没有产生明显影响。通过实验提出了去质子化的识别机理以便更好地了解反应过程。更多还原

【Abstract】 A chemosensor N4 based on hydrazone structure was designed and synthesized which could be used as an efficient colorimetric sensor for fluoride ions in aqueous solution with high selectivity and sensitivity. After the addition of fluoride ions, the color of N4 could be observed to change from yellow to light purple, while other anion ions did not change significantly, and have no effect on the identification of fluoride ions. The identification mechanism of deprotonation was proposed through experiments to better understand the reaction process.更多还原
