Synthesis and photoinduced fluorescence of 3-(2-hetarylethenyl)chromen-2-ones
摘要:
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 transformations which are accompanied by considerable change of the fluorescence pattern.
