An essential trace element copper plays several physiological roles in living systems. But at excess concentration, it exerts toxicity and becomes associated with numerous disorders. In this article, we have reviewed the recent developments (from 2017 to 2020) in the field of fluorescence-based chemosensors for the detection of Cu ion. The sensing probes which were built to work through transfer of photo-induced electron (PET), excited-state intramolecular proton (ESIPT) and Förster resonance energy (FRET) mechanisms have been included in this review. Emphasis is given on the design, sensitivity and response of the probe molecules for the detection of Cu ion. Using suitable examples, applications of these three recognition mechanisms for the probing of copper ion have been addressed.
铜是一种必需的微量元素，在生命系统中发挥着多种生理作用。但在浓度过高时，它会产生毒性，并与许多疾病有关。在本文中，我们综述了 2017 年至 2020 年期间荧光化学传感器领域在检测 Cu 离子方面的最新进展。所综述的传感探针是基于电子转移（PET）、激发态分子内质子转移（ESIPT）和Förster 共振能量转移（FRET）机制构建的。本文重点介绍了探针分子对 Cu 离子检测的设计、灵敏度和响应。通过合适的例子，讨论了这三种识别机制在探测铜离子方面的应用。
