Light-Sensitive Organic Recording Media for Three-Dimensional Optical Memory

This chapter discusses our results on the development of photochromic and photochromogenic polymer materials and recording media thereof for three-dimensional (3D) bitwise working and archival optical memory. The synthesis of original diarylethenes, fulgimides, and chromones and their characterization 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. Finally, the homemade setup for optical data writing, rewriting, and readout on the designed recording media and the results of their testing are presented.
