摘要
The present invention relates to an azobenzene compound containing nitrogen-containing heteroaromatics, a hologram recording composition comprising the same, a hologram recording medium, a hologram recording material using the same, and a hologram recording or rewriting method, wherein the azobenzene monomer compound of the present invention is produced at a green wavelength An isosorption point exists and photoisomerization occurs therefrom, and it contains a high birefringence part that can increase the refractive index change even with a small amount of light irradiation. Therefore, a polymer containing an azobenzene monomer compound is a hologram recording / by green laser irradiation. It can be usefully used as a rewritable material.
