Spectral-kinetic study of phototransformations of new 3-acyl-2-hetarylchromones

Spectral-kinetic and fluorescent properties of 16 new photosensitive compounds of the 2-furyl- and 2-thienyl-3-acylchromone classes, the initial nonluminescent forms of which undergo irreversible phototransformations into fluorescent products, are considered on the basis of their structure and properties responsible for the possibility of their application as photosensitive components of recording media for archive optical disks.
