Pyridine containing azobenzene side-chain polymers for green color rewritable hologram |
| 초록 |
The hologram is a recording of 3D information of an object, and it is attracting attention as a next-generation realistic media. Materials which are reversibly changed in refractive index or transmittance after irradiation are being studied for rewritable hologram materials. In this study, we have investigated photo-induced refractive index change characteristic polymers containing azobenezene capable of isomerization by green laser. And we devised a structure containing an acetylene group with high birefringence to increase refractive index change with low energy light irradiation. The molecular structure and physical properties of the azobenzene polymer were confirmed by NMR, UV-vis, DSC and GPC. In this presentation, the synthesis of green hologram rewritable materials and hologram recording characteristics such as diffraction efficiency and change of refractive index after light irradiation will be discussed. |
