TL;DR: A novel easily available turn-on fluorescent chemosensor RPU based on a rhodamine-phenylurea conjugate was synthesized, which showed highly selective and sensitive recognition toward Pb(2+) in CH(3)CN and Hg( 2+) in aqueous media over a wide range of tested metal ions with remarkably enhanced fluorescent intensities.

TL;DR: A Rhodamine-based fluorescent and colorimetric chemosensor for Fe3+ ion, acetyl rhodamine-hydroxamate (ARH), was designed and synthesized as mentioned in this paper.
Abstract: A Rhodamine-based fluorescent and colorimetric chemosensor for Fe3+ ion, acetyl rhodamine-hydroxamate (ARH), was designed and synthesized. Upon mixed with Fe3+ in CH3CN–H2O (1:1, v/v), the spirolactam of ARH was opened, which resulted in the dramatic enhancement of both fluorescence and absorbance intensity as well as the color change of the solution. Background metal ions showed small or no interference with the detection of Fe3+. The Job's plot indicated the formation of 1:1 complex between ARH and Fe3+. Confocal laser scanning microscopy experiments showed that ARH could be used to detect Fe3+ in living cells.

TL;DR: This comprehensive and critical review of coumarin-based small-molecule fluorescent chemosensors during the period of 2012-2018 may facilitate the development of more powerful fluorescent chemOSensors for broad and exciting applications in the future.
Abstract: 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.
