Norepinephrine is a key neurotransmitter that plays a critical role in the sympathetic
nervous system. Its misuse and lack of regulation is closely associated with the progression
of different central nervous system syndromes and neurodegenerative disorders. Herein,
a reactive probe based on an excited-state intramolecular proton transfer (ESIPT)
mechanism is reported for the selective fluorescent detection of norepinephrine under
physiological conditions and in live cells.
