Synthesis and fluorescence of 2H-pyrone derivatives for organic light-emitting diodes (OLED)

摘要

2H-Pyrone derivatives were synthesized through the reaction of aryl acetyl compounds with ketene dithioacetals in the presence of sodium hydroxide, and they showed very strong fluorescence in the solid state. The light-emitting region of these 2H-pyrones is 447-630 nm in the solid states.
