Synthesis and study of photosensitive chromone derivatives for recording media of archival three-dimensional optical memory

Abstract

The synthesis and photochemical study of 3-acetyl-2(2'-furyl)chromone derivatives are described, which are of interest for the creation of photo-induced irreversible luminescent media for one-time superdense recording on a multilayer carrier. New thiophene-containing 3-acetyl-2(2'-furyl)chromone derivatives are prepared with examples of their chemical modification and their photochemical properties studied, including spectral data for the individual substances and those incorporated in polymeric matrices. These show prospects as light-sensitive components of recording media for archival three-dimensional optical memory.
