Fluoride ions play an important role in many chemical
biological
medical and military processes because of strongest electronegativity
the smallest ion radius
and strong Lewis base. Low levels of fluoride ions have shown to be effective for prevention of dental caries and treatment of osteoporosis. But high concentration of fluoride intake is harmful to human body. It may cause dental fluorosis
skeletal fluorosis
urolithiasis and diseases such as cancers. Therefore
the recognition and detection of fluoride ions is of great significance. Fluoride fluorescent probes have attracted a wide spread attention due to its high selectivity and sensitivity
speediness and convenience
low cost
etc. In recent years
the researchers designed and synthesized a large number of fluorescent probes for fluoride ions. According to detection mechanism
fluorescent probes for fluoride ions mainly contained three types: 1) the hydrogen bond type; 2) Lewis acid style; and 3) the hydrogen bond and Lewis acid mixed. In this paper
the research progress of different types of fluorescent probes for fluoride ions respectively was reviewed
the advantages and disadvantages of different types were summed up
and the future research of fluorescent probes for fluoride ions was prospected.
