“…Compound 133 is a simple coumarin derivative with a vinyl ether group as a recognition site. The vinylether is cleaved according to the mechanism in Figure , whereas sensor 134 is based on a propargylamine. In the case of 134 , the reaction does not result in the cleavage of the propargyl group but rather transfers it into the corresponding β-ketone, as the oxymercuration reaction proceeds via a Markovnikov-type reaction mechanism.…”

Coumarins are a very large family of compounds containing the unique 2H-chromen-2-one motif, as it is known according to IUPAC nomenclature. Coumarin derivatives are widely found in nature, especially in plants and are constituents of several essential oils. Up to now, thousands of coumarin derivatives have been isolated from nature or produced by chemists. More recently, the coumarin platform has been widely adopted in the design of small-molecule fluorescent chemosensors because of its excellent biocompatibility, strong and stable fluorescence emission, and good structural flexibility. This scaffold has found wide applications in the development of fluorescent chemosensors in the fields of molecular recognition, molecular imaging, bioorganic chemistry, analytical chemistry, materials chemistry, as well as in the biology and medical science communities. This review focuses on the important progress of coumarin-based small-molecule fluorescent chemosensors during the period of 2012− 2018. This comprehensive and critical review may facilitate the development of more powerful fluorescent chemosensors for broad and exciting applications in the future.

“…The activation of alkynes by Hg 2 + species towards nucleophilic additions has long been known in synthetic chemistry as a powerful synthetic approach to accessing complex molecular structures. [41][42][43][44][45] We hypothesised that a sensing strategy capitalising on the activation of alkynes by uniquely alkynophilic Hg 2 + ions could dramatically improve the analytical performance of such probes towards Hg 2 + in terms of their selectivity, specificity and response time.…”

“…Considering all of the above, we sought a new reaction scheme that can be used as a recognition event and exploited in designing a new family of fluorescent Hg 2+ probes. The activation of alkynes by Hg 2+ species towards nucleophilic additions has long been known in synthetic chemistry as a powerful synthetic approach to accessing complex molecular structures [41–45] …”

Drawing upon an intramolecular cyclization/annulation reaction sequence mediated by Hg 2 + ions, a BODIPYbased fluorescent probe decorated with an alkynyl hydrazone motif responds rapidly and selectively to Hg 2 + ions, with a detection limit of 29 nM and a fluorescence turn-on ratio of 15-fold. With the addition of Hg 2 + ions, the BODIPY-based alkynyl hydrazone transforms into a pyrazole ring to mediate a turn-on emission response clearly observable to the naked eye under visible light excitation.
