Abstract

The invention relates to a holographic optical storage polymer and a manufacturing method thereof. The holographic optical storage polymer is a pseudostilbene-type azo polymer material containing chiral groups. The manufacture method of the holographic optical storage polymer is to use S-2-methyl-1-butanol as a chiral source, and obtain aniline derivatives with chiral groups by reacting with 4-aminobenzoic acid, and then pass Pseudostilbene-type azo monomers containing chiral groups were prepared by nitrogen coupling reaction, and finally the synthesized azo monomers were polymerized to obtain corresponding polymers by polymerization reaction. The flexible spacer between the azo group of the holographic optical storage polymer and the polymer main chain is 2-16 methylene groups. The molecular weight of the holographic optical storage polymer is adjustable. Under the irradiation of 532 nanometer interference laser, a surface quasicrystal structure of 12 layers or more can be processed on the surface of the holographic optical storage polymer, and the holographic optical storage polymer can be processed within 1 minute. Holographic optical storage is performed on the surface of the storage polymer film, and the formed holographic pattern can be erased and rewritten.
