“…Optical techniques such as absorption spectroscopy and spectrofluorimetry rely on changes in color or fluorescence intensity and are not hindered by these problems [ 14 , 15 ]. Fluorescent chemosensors for Hg 2+ ions are mainly derived from carbon dots [ 16 , 17 ], metal–organic frameworks [ 18 , 19 ], porphyrin [ 20 ], BODIPY [ 21 , 22 ], naphthalimide [ 23 ], coumarin [ 24 ], rhodamine [ 25 , 26 ], and fluorescein [ 27 , 28 , 29 ]. The development of new chemosensors for mercury ions is an important goal for researchers worldwide due to adverse environmental conditions.…”

This article discusses the design and analysis of a new chemical chemosensor for detecting mercury(II) ions. The chemosensor is a hydrazone made from 4-methylthiazole-5-carbaldehyde and fluorescein hydrazide. The structure of the chemosensor was confirmed using various methods, including nuclear magnetic resonance spectroscopy, infrared spectroscopy with Fourier transformation, mass spectroscopy, and quantum chemical calculations. The sensor’s ability in the highly selective and sensitive discovery of Hg2+ ions in water was demonstrated. The detection limit for mercury(II) ions was determined to be 0.23 µM. The new chemosensor was also used to detect Hg2+ ions in real samples and living cells using fluorescence spectroscopy. Chemosensor 1 and its complex with Hg2+ demonstrate a significant tendency to enter and accumulate in cells even at very low concentrations.

As a heavy metal ion, excessive aluminum ions pose a serious threat to human health and the ecological environment. Developing a simple, efficient, and fast detection method to detect the content of aluminum ions is of great significance, especially for ensuring human health and ecological safety. Herein, the mixed rare earth metal–organic framework (Ce0.74Eu0.26TPTC and Ce0.62Eu0.38TPTC) were prepared based on simple ligand 1,1′:4′,1″‐Terphenyl‐2′,4,4″,5′‐tetracarboxylic acid (H4TPTC). The Ce0.74Eu0.26TPTC and Ce0.62Eu0.38TPTC have dual luminescence centers, which can be used as ratio fluorescent probes to detect Al3+ ions, making the detection results more accurate and reliable. Therefore, this work can promote the further development of rare earth‐based MOFs in the detection of heavy metal ions.
