Coumarin-based Hg2+ fluorescent probe: Synthesis and turn-on fluorescence detection in neat aqueous solution

A fluorescent probe for the dual detection of mercury ions and thiols based on a simple coumarin derivative

“…The development of selective and sensitive fluorescent probes for Hg(ii) is one of the best options for their detection. [17][18][19][20][21][22][23][24][25] Recently, efficient bifunctional fluorescent probes garnered substantial interest because they can be used for the simultaneous detection of two different analytes. For example, certain bifunctional fluorescent probes were capable of sensing Hg(ii) along with another analyte such as Ag(i), 26,27 Cu(ii), [28][29][30] Fe(iii), 31 Al(iii), 32 pH change, 33 saccharides 34 or F -.…”

Synthesis and application of coumarin fluorescence probes

“…That means the probe 1 is sensitive enough to distinguish the Hg 2+ for water quality detection. 25 Qiu-juan Ma et al synthesized a rhodamine-coumarin conjugate uorescent probe 47 (Fig. 33) which with a sulfurbased functional group to detect Hg 2+ in 2010.…”

“…24 So that, it can be used to monitor water pollutions. 25 In medicine, coumarin uorescent probes can be used for intracellular biological imaging, which can then be used to detect some cancers. To date, medical imaging has made great advances in locating and discriminating tumor lesions.…”

MnSb2O6‐chitosan nanocomposite: An efficient catalyst for the synthesis of coumarins via Pechmann reaction

“…Coumarin and its derivatives have found applications as anticoagulants, as additives in food and cosmetics, and in the synthesis of insecticides . They have also found application in fluorescent probes due to their high chromogenic and fluorogenic properties …”
