Abstract
As one kind of organic photochromic optical storage material, fulgides are well-known for their thermally irreversibility. The two-photon absorption 3D optical storage technology is one of the hot research topics in the field of high-density information storage. Using optical image storage technology the recording and reading rates can be improved. In this paper, it’s found that in one kind of 3-indoly-benzylfulgimide/PMMA film, there exits two-photon absorption property. And depending on this property, the two-photon absorption photochromic optical image storage was realized in an indoly-benzylfulgimide/PMMA film. It is proved that the N-benzyl-1,3,4-trimethyl-2-(2-methyl-) indoly-fulgimide has potential application in the two-photon absorption 3D optical storage.
