Abstract
A new unsymmetrical photochromic diarylethene, 1-{2-methyl-5-[5-(2,3,5-trihydroxyl-β-D-xylosyl)-3-(1,2,3-triazolyl)] methylene-3-thienyl}-2-[2-methyl-5-(4-methoxylphenyl) methyl-3-thienyl] perfluorocyclopentene (1a), was synthesized, and its photochromic properties were investigated in detail. The compound exhibited good photochromism both in acetonitrile solution and in PMMA film with alternating irradiation by UV/vis light, and the maxima absorption of its closed-ring isomer 1b are 556 and 560 nm, respectively. There almost no fluorescence switches of 1a in acetonitrile solution and PMMA amorphous film. The diarylethene 1a has promising application for photo-switching, which can use for data storage.
