Fluorescence properties of light-sensitive chromones used in archival polymer recording media

• Fluorescence properties of light-sensitive chromone derivatives in toluene were studied.
• Fluorescence quantum yields of the photoproducts were measured.
• A relationship between the fluorescence properties of these photoproducts and structure of chromones was revealed.

The fluorescence properties of compounds formed upon irreversible photochemical transformation of some chromone derivatives in toluene were studied. At the first time, the quantum yields of the photoproducts were measured. The relationship between the fluorescence properties and the structure of these photoproducts was elucidated. It was shown that the properties of some chromones make them suitable for the design of light-sensitive recording media for optical discs with non-destructive fluorescence readout of optical information.
