“…28,29 As a result, an increasing number of papers concerning coumarin derivatives uorescent chemosensors for copper(II) ion have emerged. [30][31][32][33] In 2009, Lee Jin Yong and coworkers developed a novel coumarin-based uorogenic probe, which can act as a uorescent chemosensor with high selectivity and suitable affinity in biological systems toward Cu 2+ (ref. 34).…”

“…Cu 2+ is an essential part of the human body and is of great significance for basic physiological processes such as brain development, heart protection, maintenance of hematopoietic function and cancer prevention . Moreover, the excessive Cu 2+ content in water has a significant inhibitory effect on the self‐purification of water bodies and is detrimental to the growth of crops, especially rice and barley, and can contaminate grain grains . Apart from this, excessive of inorganic phosphate in water bodies also lead to the proliferation of edema algae, which indirectly affects the growth of fish.…”

A high-efficiency dual-functional on-off-on fluorescence probe: 2'-4'-dihydroxydiphenyl-8-formyl-7-hydroxycoumarin hydrazine (L) based on photoelectron transfer mechanism (PET) was designed and synthesized, and its ion recognition characteristics were fully studied by spectroscopy. As expected, probe L shows highly sensitive to Cu 2 + in EtOH-HEPES (20 mM v/v, 80 : 20, pH = 7.40) solution, and its detection limit up to 6.14 × 10 À 7 M. The stoichiometric ratio of LÀ Cu 2 + complex was determined as 1 : 1 based on 1 H NMR titration and ESI-MS. Meanwhile, the resulted LÀ Cu 2 + complex shows good selectivity for the phosphoric acid family anion (H 2 PO 4 À , HPO 4 2À and PO 4 3À ), which denote probe L the dual-function in rapid detection of Cu 2 + and phosphate family's ions. Scheme 1. Synthesis of probe L. (a) NH 2 -NH 2 , MeOH, room temperature, 24 h. (b) Hexamethylenetetramine, HOAc, 90°C, 8 h. (c) MeOH, room temperature, 10 h.

“…Coumarin-based chemosensors 26-28 with complex chemical architecture were designed and synthesized for selective sequential recognition of Cu 2+ and pyrophosphate anion (PPi) [55][56][57]. PPi is the main product of adenosine triphosphate hydrolysis in living cells, which is involved in important metabolic processes.…”

Fluorogenic sensors capable of selective interaction with analyte, which leads to a change in the position or intensity of the fluorescence band, allow to detect ions or molecules in situ and in vivo and possess high sensitivity and efficiency. Currently, they are widely used in organic, biological, and medical chemistry and environmental sciences for express monitoring of the ionic composition of the medium. They represent a serious alternative to the bulky, expensive, non-transportable technical devices traditionally used for this purpose, such as atomic absorption, atomic emission, and XRF spectrometers. Polyfunctional sensors capable of independent detection of two or more kinds of "guests" from a multiple mixture of cations, anions, or molecules due to specific spectral responses via the same or different channels constitute a rapidly developing area of chemosensory science. This specific feature is associated with the presence of two or more coordination centers in their molecules, or the capability of one center to selectively respond to various analytes with individual spectral changes. Coumarin (2H-chromene-2-one) core is one of the most versatile frameworks for the design of fluorogenic polyfunctional chemosensors for multianalyte detection. In this chapter, we report on the review of sensing properties of this group of chemosensors based on functionalized coumarin derivatives, including their applications in bioimaging.
