  • Preparation method and application of fluorescent compound having sensing ability to aniline and o-toluidine gas, and fluorescent film with the same
    Patent number: 10655060
    Abstract: The present invention discloses a fluorescent compound having a sensing ability to aniline and o-toluidine, a preparation method thereof, a preparation method and application of a fluorescent sensing film. The compound contains a naphthalenediimide (NDI) unit, two alkynyl aniline conjugate fragments and two long alkyl chain fragments; compared with perylene anhydride (PDI), naphthalenediimide (NDI) has better solubility, rich photophysical property, good photochemical stability and strong ?-? stacking effect; these building units make the prepared fluorescent compound have supramolecular characteristics and more abundant gelling behavior and assembly behavior. Therefore, the sensing film prepared with the fluorescent compound is controllable in the microstructure, good in stability, high in sensitivity, long in service life and able to be repeatedly used.
