A novel photochromic diarylethene, 1-(2-ethyl-3-benzothienyl)-2-( 2-methoxylphenyl)perfluorocyclopentene(1a) was synthesized and its photochromic and fluorescent properties were investigated. This compound showed good photochromism both in solution and in PMMA amorphous film. In hexane solution, the open-ring isomer of the diarylethene 1 exhibited relatively strong fluorescence at 363 nm when excited at 327 nm. This new photochromic compound also exhibited remarkable fluorescence switching in the solid state. Using diarylethene 1b/PMMA film as recording medium, the evaluation of potential of photochromic diarylethene as a polarization medium by recording and reading in a real-time operation was investigated.The results demonstrated that the diarylethene compound had attractive properties for high density optical storage.
