“…The Hg 2+ fluorescent probe was constructed and reported by applying the well-known specific Hg 2+ -triggered thioacetal deprotection reaction to generate the formyl group. 47 − 49 A 1,2-dithioalkyl group was chosen as the specific recognition site of Hg 2+ . When there was no mercury ion, the probe showed weak fluorescence and the color of the solution was light yellow.…”

Hg 2+ has a significant hazardous impact on the environment and ecosystem. There is a great demand for new methods with high selectivity and sensitivity to determine mercury in life systems and environments. In this paper, a novel turn-on Hg 2+ fluorescent probe has been reported with a naphthalimide group. The Hg 2+ fluorescent probe was designed by the inspiration of the well-known specific Hg 2+ -triggered thioacetal deprotection reaction. A 1,2-dithioalkyl group was chosen as the specific recognition site of Hg 2+ . The probe showed weak fluorescence without Hg 2+ , and the color of the solution was light yellow. In the presence of Hg 2+ , the probe reacted specifically with the mercury ion to produce an aldehyde and emitted strong fluorescence, and the color of the solution also turned light green, thus realizing the monitoring of the mercury ion. The Hg 2+ fluorescent probe showed outstanding sensitivity and selectivity toward Hg 2+ . Furthermore, the Hg 2+ fluorescent probe could work in a wide pH range. The linear relationship between the fluorescence intensity at 510 nm and the concentration of Hg 2+ was obtained in a range of Hg 2+ concentration from 2.5 × 10 –7 to 1.0 × 10 –5 M. The detection limit was found to be 4.0 × 10 –8 M for Hg 2+ . Furthermore, with little cell toxicity, the probe was successfully applied to the confocal image of Hg 2+ in PC-12 cells.

“…Therefore, designing molecular chemosensors for mercury ions is a very important endeavor, especially in aqueous systems, as certain biological species readily convert metallic mercury into organic mercury. There have been many different types of fluorescent sensors for mercury, recent examples include quantum dots [189], biosensors [8], carbon dots [190], carbon nanoparticles [191], gold and silver nanoparticles [192,193], but the focus in this final section is on LMFP sensors.…”

Low Molecular Weight Fluorescent Probes (LMFPs) to Detect the Group 12 Metal Triad

2019

Fluorescence sensing, of d-block elements such as Cu2+, Fe3+, Fe2+, Cd2+, Hg2+, and Zn2+ has significantly increased since the beginning of the 21st century. These particular metal ions play essential roles in biological, industrial, and environmental applications, therefore, there has been a drive to measure, detect, and remediate these metal ions. We have chosen to highlight the low molecular weight fluorescent probes (LMFPs) that undergo an optical response upon coordination with the group 12 triad (Zn2+, Cd2+, and Hg2+), as these metals have similar chemical characteristics but behave differently in the environment.

“…In the first type of sensor, the interactions between a ligand and Hg 2+ results in changes in fluorescence ( Figure 1A). The main disadvantage of this type of sensor is its vulnerability to interference from other metal ions, especially Cu 2+ , Cd 2+ , and Fe 3+ Kau et al, 2012;Rao et al, 2012;Zhang et al, 2013;Kim et al, 2014;Fang et al, 2016;Alibert et al, 2017;Huang et al, 2019). In the second type of sensor, special chemical reactions (e.g., desulfurization between the ligands and Hg 2+ ) generate a new product with a different fluorescence spectrum (Figure 1B).…”

A Fluorescent and Colorimetric Chemosensor for Hg2+ Based on Rhodamine 6G With a Two-Step Reaction Mechanism

A fluorescent and colorimetric chemosensor L based on rhodamine 6G was designed, synthesized, and characterized. Based on a two-step reaction, the chemosensor L effectively recognized Hg 2+ . The interaction between the chemosensor and Hg 2+ was confirmed by ultraviolet-visible spectrophotometry, fluorescence spectroscopy, electrospray ionization-mass spectrometry, Fourier-transform infrared spectroscopy, and frontier molecular orbital calculations. The chemosensor L was also incorporated into test strips and silica gel plates, which demonstrated good selectivity and high sensitivity for Hg 2+ .
