Mercury is a frequent, bioaccumulative, extremely toxic pollutant in the environment. Mercury contamination can be accumulated along the food chain and cause a wide range of serious threats to living organisms, and also affect neurological systems and the kidneys. The trace-level detection of heavy and toxic metal ions such as mercury ions is certainly great intense. Chromogenic and fluorogenic recognition of toxic mercury ions has been established to be powerful methods due to their high detection limit, cost-efficiency, simplicity, and applicability in bioimaging. This review will mainly focus on the sensing mechanisms of fluorescent probes that have emerged over the past 5 years, such as PET, ICT, AIE, as well as ring-opening sensing mechanisms.
