3-(2-Hetarylethenyl)chromen-2-ones were synthesized for the first time, following two different schemes, and their spectral and photochemical properties were studied. The title compounds were found to undergo both reversible and irreversible photoinduced

The hitherto unknown 3-styrylcoumarin system has been synthesised by two routes.In the first approach, coumarin-3-acetic acids are reacted with aromatic aldehydes to yield directly the 3-styrylcoumarins.The synthesis is limited by the difficulty in obtaining coumarin-3-acetic acids in good yields.The second approach utilises 3-phenacylcoumarins which are reduced to the carbinols and subsequently dehydrated to the corresponding 3-styrylcoumarins.The fluorescence of these compounds and their application to polyester fibre have been studied.
