A fluorescent probe for hypochlorite based on the modulation of the unique rotation of the N-N single bond in acetohydrazide

Herein, a novel signaling mechanism for constructing fluorescent probes was demonstrated for the first time based on modulation of the unique rotation of the N-N single bond in the acetohydrazide group. According to the new signaling mechanism, a fluorescent probe for hypochlorite was then judiciously developed.
