Halogen ions play an important role in chemistry, biology and material. The concentration of fluoride in the organism directly affects its health. The halide materials often act as flame retardant to improve the ignition point for plastic and other polymer products. So it is of great significance to detect halogen ions. Chemosensors include colorimetric and fluorescent sensors, which have the advantages of good selectivity and high sensitivity. In recent years, some halogen ion chemosensors have been reported widely. According to the type of host and guest molecules, halgen ion chemosensors mainly include fluoride ion chemosensors, iodine ion chemosensors, dual channel chemosensors and functional chemosensors. In this paper, the progress of halogen ion chemosensors in recent years is reviewed, the synthetic strategies for them are summarized and the future research direction of halogen ion chemosensors is prospected.
Key words: halogen ion, guest, chemosensor
