Synthesis and properties of Green laser photoswitchable azobenzene polymer for rewritable hologram with high diffraction efficiency. |
| 초록 |
The cis-trans photoisomerization of azobenzene is well-defined and extensively applied process. Irradiation with light produces the cis isomer, which has a bent conformation and much larger dipole moment. As a result of photoisomerization of azobenezene, the polymer bearing azobenzene as a side-chain have refractive index change. In this study, we have investigated azobenzene containing photo-induced refractive index changing polymers. To increase refractive index change under low energy photoirradiation, we designed and synthesized functional group azobenzene having acetylene group which has high birefringence. The molecular structures and properties of polymers were characterized by NMR, UV-vis, DSC and GPC. The refractive index change properties of prepared polymers and rewritable hologram performance were also studied. Our developed substituted azobenzene polymer will be utilized to rewritable hologram by green laser(532nm). |
