Synthesis, Photochromism and Holographic Optical Recording of a Photochromic Diarylethene with a Chlorine Atom
A new unsymmetrical photochromic diarylethene 1-(2-methyl-benzothiophenyl)- 2-(2-methyl-5-(2-chlorophenyl))perfluoroncyclopentene (1a), was synthesized and its optoelectronic properties, such as photochromism in solution as well as in poly-methylmethacrylate (PMMA) amorphous films, fluorescences and the fluorescence spectra of diarylethene 1a depended on the concentration were investigated. Using diarylethene 1/PMMA film as recording medium and a linearly polarized 633 nm laser diode for recording and readout, polarization multiplexed image recording can be carried out in this film, which illustrated that the diarylethene can be potentially used as holographic optical recording medium.
