Provided are a near-infrared II organic fluorescent probe, and a preparation method therefor and the application thereof. The fluorescent probe and an organic coating agent are mixed to prepare a nano-imaging reagent, which has good biocompatibility and biological stability; and the nano-imaging reagent has a high molar extinction coefficient and a high quantum yield, and has bright near-infrared II fluorescence under white-light excitation. Furthermore, the nano-imaging reagent can implement high-resolution imaging of blood vessels under white-light excitation. In addition, white light is used as an excitation light source during imaging, such that problems such as limited photon absorption, laser-induced biological damage and non-uniform irradiation caused by a single-wavelength excitation light source can be effectively avoided. Moreover, a laser light source is costly, while a white light source is cheaper and more readily available. Therefore, the nano-imaging reagent can be used for developing a high-performance biological imaging contrast agent, holding broad prospects in the field of in-vivo imaging for non-diagnostic and non-therapeutic purposes.
