AI Technical Summary
Existing technologies make it difficult to prepare functionalized polysiloxanes with atypical blue-green fluorescence, and existing detection methods such as chromatography are time-consuming and photometric methods are costly, which limits their application in pesticide detection.
A β-hydroxyl-containing furanyl polysiloxane is generated by a mercapto-epoxy click chemical reaction using epoxy-based polysiloxane and mercaptofuranyl compounds. The spatial conjugation is increased by hydrogen bonding, resulting in blue-green fluorescence, and the fluorescence intensity is enhanced by interaction with trifluralin.
A functionalized polysiloxane with atypical blue-green fluorescence was prepared, which expanded the emission band and enabled efficient detection of trifluralin pesticide, simplifying the detection process.
