Fluorescent chemosensors received more and more attention because these kinds of chemosensors possess a lot of advantages such as high sensitivity, realize tele-monitor and real-time detection. It was also used as signal output in ion recognition. With the rapid development of host-guest chemistry, a series of fluorescent sensors with good properties have been reported. In this review the research progress of fluorescent chemosensors in terms of recognition principle for ion recognition in resent five years was briefly reviewed based on intramolecular charge transfer (ICT), photoinduced electron transfer (PET), fluorescence resonance energy transfer (FRET), excited-state intramolecular proton transfer (ESIPT), monomer-excimer (EM) and chelation-enhanced fluorescence (CHEF), etc. The developing orientation for further research is presented. Keywords fluorescent sensor; ion recognition; intramolecular charge transfer (ICT); photoinduced electron transfer (PET); fluorescence resonance energy transfer (FRET); excited-state intramolecular proton transfer (ESIPT); monomer-excimer; chelation-enhanced fluorescence (CHEF)

“…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 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+ .

A novel long-wavelength turn-on fluorescent chemosensor CS based on pyrene was synthesized to detect Hg2+. In the presence of other metal ions, CS could effectively recognize Hg2+ and produce the turn-on fluorescent emission at 607 nm. Also, the absorption spectrum exhibited red-shift. Meanwhile, the change of the solution color from yellow to orange was directly observed by the naked eye. The interaction between CS and Hg2+ was confirmed by the Job’s plot, electrospray ionization mass spectrometry, scanning electron microscopy, and density functional theory calculations. It was found that the fluorescence of CS could be reversible when I– was added into the solution of CS and Hg2+. CS illustrated high selectivity and good sensitivity for Hg2+ with the limit of detection of 36 nm. Moreover, CS could be utilized as test strips and silica gel plates to identify Hg2+.
