2H-Pyronederivatives 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.

A simple yet convenient nucleophile-induced synthetic route for the construction of thermally stable fluorescent functionalized stilbenes from α-pyranones and aryl ketones has been delineated. The nucleophile-induced base encourage synthetic protocol was performed under mild conditions without harming the environment and products were achieved in good yields. The synthesized stilbenes showed amazing
