. The structure and properties of complex
1
were characterized by X-ray single crystal diffraction, infrared spectroscopy, thermogravimetric analysis, etc., and its fluorescence detection ability for streptomycin was analyzed in depth.
The analysis results of X-ray single crystal diffraction reveal that it crystallizes in the

, due to its excellent fluorescence properties and stability, can be used for selective detection of streptomycin. The fitting results show that
