Fluoride and cyanide contamination in drinking water imposes detrimental impacts on human health above their permissible limits. Hence, the quantitative detection of these colourless water-soluble toxins has attracted attention. Even though a plethora of chemosensors have been reported so far for the detection of fluoride and cyanide from various matrices, still their applicability is limited to a few examples. Nevertheless, recent advances in the syntheses of coumarin derivatives have shown significant impact on fluoride and cyanide detection. Therefore, this present review provides a brief overview of the application of coumarin-coupled molecular scaffolds towards the detection of perilous fluoride and cyanide along with their sensing mechanisms in order to develop more innovative, simple, sensitive, real-time responsive and cost-effective coumarin-based supramolecular chemosensors to promote next generation approaches towards the ultra-trace quantitative detection of these toxic anions.
饮用水中氟化物和氰化物的污染超过其允许限度，会对人类健康造成有害影响。因此，对这些无色水溶性毒素的定量检测引起了人们的关注。尽管迄今为止已经有大量的化学传感器被报道用于从各种基质中检测氟化物和氰化物，但它们的适用性仍然局限于少数几个例子。然而，香豆素衍生物合成方面的最新进展表明，它们对氟化物和氰化物的检测有显著的影响。因此，本综述简要概述了香豆素偶联分子支架在检测危险氟化物和氰化物方面的应用，以及它们的传感机制，以开发更具创新性、简单、灵敏、实时响应和具有成本效益的基于香豆素的超分子化学传感器，促进下一代方法对这些有毒阴离子的痕量定量检测。
