Optical polymer materials with photocontrolled fluorescence

• Polymer layers with photoinduced fluorescence were prepared and studied.
• Layers with diarylethenes and fluorophors may be used in working optical memory.
• Layers based on chromones are intended for archival optical memory.
• Developed layers provide making multilayer optical disks (ODs) of new generation.
• ODs have a super high capacity and nondestructive fluorescent readout.

The results of the development of optical fluorescent solid film materials for applications as recording media for two-photon three-dimension bitwise optical memory with nondestructive fluorescent readout are presented. It was shown that photochromic diarylethenes in combination with organic fluorophore phenalenone or inorganic quantum dots CdSe/ZnS provide preparation of multilayer optical disks for working optical memory. Polymer layers based on irreversible light – sensitive chromones are acceptable for making optical disks of the archival type.
