Highly activated Michael acceptor by an intramolecular hydrogen bond as a fluorescence turn-on probe for cyanide.
An activated Michael acceptor type of probe by an intramolecular hydrogen bond has shown a selective fluorescence turn-on response to cyanide through a conjugated addition of the nucleophilic anion to the enone probe with a 1300-fold increase in its fluorescence intensity.
