Diaminomaleonitrile substituted pyrene as a solvent-dependent chemosensor for copper(II) ion and hypochlorite

Pyrene‐based ratiometric fluorescent chemosensor for sensitive detection of hypochlorite in a perfect aqueous solution

“…In particular, reaction sites containing hydrazones [41,42], chalcogenides [43][44][45], and C C bonds [46][47][48] susceptible to ClO À through the hydrolytic cleavage or oxidation reaction are used as part of chemosensors. Moreover, unique fluorescence responses were induced using diverse fluorophores such as coumarin [10], rhodamine [49], BODIPY [50], and pyrene [51]. Among them, the pyrene moiety with good photostability and high quantum yield was selected as a fluorophore and used for the development of a fluorescent chemosensor for ClO À [51][52][53][54].…”

However, many pyrene-based fluorescence chemosensors for detecting ClO À suffer from poor water solubility [52,53].…”
