Synthesis and properties of azobenzene containg polymer for blue updatable hologram |
초록 |
When the azobenzene group absorbs the light, cis-trans photoisomerization occurs. As a result of photoisomerization, azobenzene containg polymer have a refractive index change after photo-irradiation. Using such reversible refractive index change characteristics, the azovenzene polymers were studied as one of rewritable hologram materials. In this study, we designed a molecular structure that maximizes the refractive index modulation by photoisomerization under the blue laser wavelength (~ 460 nm), and azobenzene containg PMMA based polymer was synthesized. The molecular structure and physical properties of the polymer used as the blue hologram rewritable material were characterized by NMR, UV-vis, DSC and GPC, and the hologram recording characteristics such as diffraction efficiency and refractive index change after photo-irradiation were also studied. |
