Heavy metal detection by sensing technology is an important field of research as the heavy metals are toxic and are found in the environmental matrix. The detailed structure and sensing property studies of the probes enhance the knowledge for the future design and development of a probe for same metal. In this review, we have discussed about different chemo and fluorosensors for copper detection and their sensing parameters in different media with detailed structural studies. The removal of copper from the water medium is also addressed in this review. Application of membrane process, adsorption, and electrocoagulation along with their implementation challenges are discussed.

“…Another approach was attempted for the selective detection of copper (II) ions by He et al in 2018, which based the fluorescent probe on a coumarin-Schiff base derivative (186, Figure 60). This probe resulted to be particularly selective for Cu 2+ even in the presence of several other ions [242]. Saravana Mani and colleagues designed in 2019 a coumarin hydrazine-based fluorescent probe for the detection of copper(II), called BENZEPYR (187, Figure 60), exploiting a reaction of condensation between 2-hydrazino benzothiazole and N,N -diethylamino-3-acetyl coumarin [243].…”

Privileged structures have been widely used as an effective template for the research and discovery of high value chemicals. Coumarin is a simple scaffold widespread in Nature and it can be found in a considerable number of plants as well as in some fungi and bacteria. In the last years, these natural compounds have been gaining an increasing attention from the scientific community for their wide range of biological activities, mainly due to their ability to interact with diverse enzymes and receptors in living organisms. In addition, coumarin nucleus has proved to be easily synthetized and decorated, giving the possibility of designing new coumarin-based compounds and investigating their potential in the treatment of various diseases. The versatility of coumarin scaffold finds applications not only in medicinal chemistry but also in the agrochemical field as well as in the cosmetic and fragrances industry. This review is intended to be a critical overview on coumarins, comprehensive of natural sources, metabolites, biological evaluations and synthetic approaches.

“…In recent years, a number of highly effective fluorescence probes based on coumarin derivatives have been developed due to their high fluorescence quantum yield and large stokes shift [32,33]. And the spectra of coumarin derivatives could be easily modified to fall well within the visible range.…”

A novel coumarin-based compound DPAC with two dipicolylamine (DPA) arms as the chelator sites was designed and synthesized. The compound DPAC exhibits a highly selective response to Cu2+ ions with a distinctly emission-quenching phenomenon. Moreover, the in situ formed complex DPAC-Cu2+ was used for the detection of pyrophosphate (PPi). The binding manner of probe DPAC-Cu2+ with PPi in 1 : 1 stoichiometry was supported by the Benesi-Hildebrand fitting, ESI-MS and HPLC analysis. The linear range of PPi concentration was 1-4 μM, and the detection limit was 0.53 μM. The competing experiments illustrated that the probe DPAC-Cu2+ had good sensitivity and selectivity for PPi than other anions, including ATP, ADP, AMP, and Pi in CH3CN : HEPES (3 : 2, v/v, pH=7.20) buffer. Further, cell fluorescence imaging experiments indicated that the probe DPAC-Cu2+ had a potential to be used to detect PPi in vivo.
