제목 Green laser recordable acetylene containing large refractive index changing azobenzene polymers for rewritable hologram
초록 A hologram is a result of recording three-dimensional stereoscopic images using the interference effect of light caused by two laser beams. Silver halide, DCG, photopolymer, and photoresist have been used as hologram writing materials having refractive index change after laser exposure. However currently invented Material is difficult to implement updatable. In this research, we have investigated to develop holographic rewritable materials using refractive index change followed by cis-trans photoisomerizaion of azobenzene. We designed and synthesized green laser photoswitchable azobenzene having acetylene group which has high birefringence. The synthesized monomers and polymers were characterized by NMR, MS UV-vis, TGA and DSC . The refractive index change properties of prepared polymers and rewritable hologram performance were also studied. Our developed material will be utilized to rewritable hologram by green lase(532nm).
