Light-sensitive heterocyclic compounds for information nanotechnologies

We showed previously that derivatives of 3-acetyl-2-furylchromones are promising components of recording media for providing a single two-photon record on multilayer optical disks of ultra-high information capacity [1,2]. It is known that 3-acetyl-2-furylchromones in the initial form A do not possess fluorescence, but on irradiation with UV light undergo irreversible photochemical conversion with the formation of the fluorescing form B [1-4], which provides multiple fluorescent reading of optical information.In the present work we have continued the study of the effect of structural factors on the photochemical properties of 3-acyl-2-furylchromones. In the previous investigation it was shown that the spectral characteristics of chromones depend to a significant extent on the substituents in the furan ring. The introduction of halogen atoms or a nitro group leads to a strong bathochromic shift of the absorption band of the initial form A, and also a shift of the absorption and fluorescence band of the photoproduct B [2]. It seemed expedient to study the effect of donor groups on the photochemical and fluorescent properties of chromones.
