Methods were developed for the synthesis of 1-aryl-9H-thieno [3, 4-b] chromon-9-ones based on the reaction of bromo and dibromo derivatives of 2-methyl-4H-chromon-4-one with thioacetamide in DMF. The thienochromones were modified and their fluorescence properties were studied. Bis (thienochromones) were synthesized by the reaction of thienochromones with ketoaldehydes.
