Anti AIE single molecule fluorescent switches for detection of heavy metal ions

AIE fluorescent sensor for the detection of heavy metal ions based on the fold/unfold conformational transition of AIE molecular modules in a single molecule triggered by the coordination of heavy metal ions. The fluorescent probe is able to detect a range of heavy metal ions at concentrations well below the "Hygienic Standard for Drinking Water", and is expected to be used as a fluorescent probe with a new detection mechanism for heavy metal ions for environmental detection or bio-monitoring applications.
