文摘
- •
Novel fluorescent 6-(4-dialkylamino)phenyl-2-pyridones were synthesized by a one-pot method.
- •
All the compounds showed positive solvatofluorochromism.
- •
Intense fluorescence was observed in polar and nonpolar solvents.
- •
The sulfonyl group disturbed the molecular planarity, resulting in intense fluorescence in polar solvents.
