A unsymmetrical photochromic diarylethene, 1-(2-methyl-5-phenylthien-3-yl)-2-[2-methyl-5-(3-fluorophenyl)thien- 3- yl]perfluorocyclopentene (1a), was synthesized and its structure was determined by single-crystal X-ray diffraction analysis. The compound showed good photochromism in solution, in PMMA amorphous film and in the singlecrystalline phase upon photo-irradiation. Using the diarylethene 1b/PMMA film as recording medium and a nonpolarized He-Ne laser (633 nm, 4 mW) for recording and readout, three types of polarization holographic optical recording were carried out successfully. The results showed that different patterns can be displayed with differently polarized readout lights, which can be applied in camouflage technology.
