n recent years, the prospects of an increase in the capacity
of data storage media (up to 1 Tera-bytes/cm3) are related
to the development of multilayer light-sensitive optical discs
using light-sensitive organic compounds for data recording
and readout. Preparation of the effective com-pounds,
which undergo photochemical transformations providing
3D operative and archival op-tical memory with ultra-high
storage capacity due to non-destructive fluorescence readout,
is one of the key problems of molecular electronics. This
presentation discusses our results on the de-velopment of
photochromic and photochromogenic polymer materials
and recording media thereof for three-dimensional (3D)
bitwise working and archival optical memory. The synthesis
of original chromones and their analogues, photochromic
diarylethenes, as well as their charac-terization are reported.
The results of spectral-kinetic studies were applied to
the development of polymeric recording layers based on
the synthesized compounds and the design of multilayer
recording media for optical disks. We demonstrated that
UV-irradiated acylchromones and their analogues that
show no fluorescence irreversibly rearrange into fluorescent
furano[3,4-b] chromenones II. Based on the latter, we have
developed multilayered recording media for optical discs of
the WORM type.
