The invention discloses a fluorescence probe for detecting nitrosyl peroxide by utilizing amido bond rupture and application of the fluorescence probe and relates to fluorescence probes of which fluorescence wavelengths have obvious displacement in the presence of ONOO<->. The invention provides a fluorescence probe capable of selectively detecting ONOO<-> in cells. A BODIPY dye and a naphthalimide dye serve as fluorescence matrixes respectively, an o-benzene selenium (tellurium) benzamide structure is introduced to serve as an activity center reacting with ONOO<->, and the ONOO<-> is selectively detected by utilizing the process of rupturing the amido bond after oxidization of organic selenium (tellurium) ether. Moreover, the influence on the fluorescence wavelength of the whole compound serves as a detection signal for probe identification before and after the amido bond rupture, and the probe is used for detecting fluorescence imaging of the ONOO<-> in the cells.
