Abstract

A new symmetrical photochromic diarylethene, 1-[2-methyl-5-(3-cyanophenyl)-3-thienyl]-2-[ (2-trifluoromethylphenyl)] perfluorocyclopentene(1a), was synthesized, and its photochromic properties were investigated in detail. The compound exhibited good photochromism both in solution and in PMMA film with alternating irradiation by UV/VIS light, and the maxima absorption of its closed-ring isomer 1b are 542 and 553 nm, respectively. Especially, the cyclic voltammetry tests demonstrated that the colorless open-ring isomers were assigned to the unique oxidation process, but the color closed-ring isomers of the compounds were assigned to two oxidation processes. Using diarylethene 1b/PMMA film as recording medium and a He-Ne laser (633 nm) for recording and readout, three types of polarization holographic optical recording were performed perfectly. The experiment demonstrates that diarylethene /PMMA films can be used to hide and display two differently polarized patterns, which may be applied in optical recording and camouflage technology.
