Two new oxadiazole derivative compounds (SiOXD1 and SiOXD2) containing dimethylsilyl units were designed and synthesized to improve the fluorescence and thermal stability of the compounds. The chemical structures of the compounds were confirmed by modern spectroscopy and X-ray diffraction analysis. The chemical structures of the compounds were characterized by Fourier transform infrared spectroscopy, fluorescence spectroscopy, ultraviolet spectroscopy and nuclear magnetic resonance spectroscopy. Thermal stability. The analytical results show that the two compounds show good fluorescence properties, and the fluorescence absorption wavelengths are about λ280 ~ 325nm and λEM300 ~ 345nm, respectively. Thermogravimetric analysis shows that the weight loss temperature range of the two materials are in the range of 110-260 ° C and 130-260 ° C respectively under air atmosphere.
