“…Mercury is a metal element that exists widely in nature. It usually has three forms in living organisms and the environment, including elemental mercury, inorganic mercury and organic mercury . As one of the most serious heavy metal pollutants, more and more attention has been attracted to mercury pollution, due to its bioaccumulation, durability, long residence, and easy transference .…”

Currently, the fluorescent probe is an important method for detecting heavy metal ions, especially mercury ion (Hg ), which is harmful to the health of humans and the environment due to its toxicity and extensive use. In this paper, we designed and synthesized a colorimetric and long-wavelength fluorescent probe Hg-P with high sensitivity and excellent selectivity, which could detect Hg by the changes of visual color, fluorescence and absorption spectroscopy. With the addition of Hg to probe Hg-P solution, its color changed from yellow to pink, and showed a 171 nm red-shifted absorption spectrum. Probe Hg-P was used in real water and soil solution samples to detect Hg , and the result is satisfactory. Therefore, this new probe shows great value and application in detecting Hg in the environment.

“…According to the 3 σ method (limit of detection (LOD) = 3 σ / K, σ represents the standard deviation of a blank solution and K represents the slope of the calibration curve in Supplemental Figure S1), the LOD of chemosensor LS for Hg 2+ reached 0.81 nM, which is much lower for the detection of Hg 2+ than other published Hg 2+ chemosensors (Table 1). 30–37 These results demonstrate that sensor LS could be potentially used for selective detection of trace amounts of Hg 2+ in analytical chemistry.…”

A novel coumarin-derived dithioacetal chemosensor, 8-(1,3-dithian-2-yl)-7-hydroxy-4-methylcoumarin (LS), has been designed and synthesized. The sensor LS showed highly selective fluorescent sensing for Hg2+ with a low detection limit of 0.81 nM in the pH range from 6.15 to 9.96 in ethanol/water (1:1, v/v) solution. The sensing mechanism of LS toward Hg2+ was proposed and verified by 1H nuclear magnetic resonance spectroscopy studies. Under an ultraviolet lamp, the fluorescence color changes could be easily detected by the naked eye. In addition, the sensor LS has been applied in the trace detection of Hg2+ in real water samples.

“…Small organic fluorophores are indispensible tools for the construction of fluorescent probes because of the controllable optical properties such as bodipy, coumarin, rhodamine, fluorescein, etc . Among them, fluorophores derived from benzothiazole are widely used as the dye platform for designing of fluorescent probes . In our previous work, a ratiometric fluorescent probe HBT‐FA for sensing formaldehyde based on intramolecular charge transfer (ICT) mechanism by using aza‐cope reaction was constructed, which showed good ratio signals in aqueous and calf serums .…”

A new Light‐Up fluorescent probe (FA‐P) for detection of formaldehyde was designed and synthesized based on the donor‐excited photo induced electron transfer (d‐PeT) process. The probe FA‐P was constructed by integrating a benzothiazole derivatives as the fluorescent skeleton and homoallylamino group as the specific recognition site. It showed the unique advantages of easy‐preparation, and excellent selectivity response toward formaldehyde. Besides, The probe FA‐P can not only detect formaldehyde gas through the prepared test paper, but also detect formaldehyde in serum solution.
