  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.

  2 H-吡喃酮衍生物是通过芳基乙酰基化合物与乙烯酮二硫缩醛在氢氧化钠的存在下反应合成的，它们在固态时显示出非常强的荧光。在固态下，这两个H-吡喃酮的发光区域为447-630 nm。
