Abstract

The invention relates to a holographic optical storage polymer and a manufacturing method thereof. The holographic optical storage polymer is a pseudo-stilbenes type azo polymer material containing chiral groups. The manufacturing method of the holographic optical storage polymer comprises the following steps: using S-2-methyl-1-butanol as a chiral source to react with 4-aminobenzoic acid to obtain an aniline derivative with chiral groups, then preparing a pseudo-stilbenes type azo monomer containing chiral groups through a diazo coupling reaction, and finally, polymerizing the synthesized azomonomer by polymerization to obtain the corresponding polymer. The flexible spacer groups between the azo group of the holographic optical storage polymer and the polymer main chain are 2-16 methylene groups. The molecular weight of the holographic optical storage polymer can be adjusted, and under the irradiation of a 532-nanometer interference laser, the surface quasi-crystal structure of 12 times or more can be processed on the surface of the holographic optical storage polymer, holographic optical storage can be performed on the film surface of the holographic optical storage polymer in 1minute, and the formed holographic pattern can be erased and rewritten.
