| 제목 | Synthesis and properties of photoinduced refractive index chnage polymers |
| 초록 | Refractive index changing materials by photo-irradiation or electrical field were widely utilized to optical, electrical and biological applications. The trans-cis 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 azobenzene, the polymer bearing azobenzene as a side-chain have a large refractive index change. In this study, we have investigated azobenzene containing photo induced refractive index change polymers. The methacrylate monomers and azobenzene side chain polymers with various ratio were synthesized via radical polymerization. The molecular structure and properties of polymers were characterized by NMR, UV-vis, DSC and GPC. The refractive index change properties of prepared polymers after UV-irradiation were also studied. |
