Latest Patents

Jiayun Fan holds a patent for the "Preparation method and application of fluorescent compound having sensing ability to aniline and o-toluidine gas, and fluorescent film with the same." This invention discloses a fluorescent compound that possesses the ability to sense aniline and o-toluidine gases. The compound includes a naphthalenediimide (NDI) unit, two alkynyl aniline conjugate fragments, and two long alkyl chain fragments. Compared to perylene anhydride (PDI), NDI offers better solubility, rich photophysical properties, good photochemical stability, and a strong π-π stacking effect. These characteristics enable the prepared fluorescent compound to exhibit supramolecular properties and enhanced gelling and assembly behaviors. The resulting sensing film is controllable in microstructure, stable, highly sensitive, long-lasting, and reusable. This invention allows for the sensitive and reversible detection of aniline, laying a solid foundation for the realization of an aniline fluorescence sensor.
