Abstract

A new photochromic diarylethene bearing an isoxazole unit has been synthesized, namely {1-(3,5-dimethyl-4-isoxazolyl),2-[2-methyl-5-(4-trifluoromethylphenyl)-3-thienyl]}perfluorocyclopentene. Its properties, including photochromic reactivity and fluorescence property both in solution and in PMMA film were investigated. It underwent reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light both in hexane and in PMMA. The isomeric compound also functioned as a fluorescence switch by photoirradiation both in solution and in PMMA film.
