研究目的
Investigating the synthesis and fluorescent behavior of 1,3-azaphosphole oxides and sulfides with pyrrolo[1,2-a]quinoline skeletons for optical applications.
研究成果
1,3-Azaphosphole oxides and sulfides with pyrrolo[1,2-a]quinoline skeletons were successfully synthesized and showed promising fluorescent properties for optical applications, including electroluminescent devices and bioimaging.
研究不足
The study did not isolate intermediate compounds 6 or 2, and the fluorescence quantum yields of oxides were higher than those of sulfides, indicating potential limitations in the application of sulfides.
