The pursuit of efficient schemes for recognition of physiologically and environmentally important analytes has led to extensive development in the field of supramolecular chemistry. Among various analytes, anions play a fundamental role in many biological processes. However, designing of functional chemosensors for recognition of anions is a major challenge owing to different parameters such as larger size and varying geometries. This review is focused on the development of chemosensors containing NH-binding sites for application in anion sensing and discusses the variation in selectivity as a consequence of structural modification. The mechanism of action for recognition of different anions has also been provided.

对识别生理和环境重要分析物的有效方案的追求已导致超分子化学领域的广泛发展。在各种分析物中，阴离子在许多生物过程中都起着基本作用。然而，由于不同的参数，例如较大的尺寸和不同的几何形状，设计用于识别阴离子的功能化学传感器是一个重大挑战。这篇综述的重点是用于阴离子传感的包含NH-结合位点的化学传感器的开发，并讨论了由于结构修饰而导致选择性的变化。还提供了识别不同阴离子的作用机理。
