In this paper, diarylethene derivative, 1,2-bis(2-methyl-5-N,N-dimethylaminophenyl)-thien-3-yl) perfluorocyclopentene (BMDTP) was synthesized. And the PMMA film of 10μm thickness of BMDTP was fabricated by spin-coating method. The maximal UV-Visible absorption of amorphous PMMA film is 634nm. And the reflective index modulation(Δn) is 2.14×10-3 between the open- and close-rings form. On the PMMA film, ten gratings of hologram are recorded in one volume by angle multiplexing. Therefore, the diarylethene is a promising material for rewritable volume holographic optical storage.
