The invention discloses fluorescent compounds with sensing functions for anilines and o-toluidines, and preparation and application of a fluorescent sensing film of the fluorescent compounds. The compounds contain a naphthalene anhydride unit, an alkynyl aniline conjugated segment and a long alkyl chain structure segment. Compared with the perylene anhydride, the naphthalene anhydride has the advantages of higher solubility, abundant photo-physical properties, high photochemical stability and high pi-pi accumulative action. By using the structure units, the prepared fluorescent compounds have supramolecular characteristics, and abundant gelation behaviors and assembly behaviors. Therefore, the sensing film prepared from the fluorescent compounds has the advantages of controllable microscopic shape, favorable stability, high sensitivity and long service life, and is reusable. The fluorescent compounds implement sensitive detection on anilines, and more importantly, the detection is completely reversible, thereby laying a solid foundation for implementing aniline fluorescent sensors.
