Synthesis, Properties and Application in Optical Recording of a New Diarylethene Bearing an Isoxazole Unit

Abstract:

A new photochromic diarylethene bearing an isoxazole unit has been synthesized, namely {1-(3,5-dimethyl-4-isoxazolyl), 2-[2-methyl-5-(3-methoxyphenyl)-3-thienyl]}perfluorocyclopentene. Its properties, including photochromic reactivity both in solution and in PMMA film, photoconversion ratio at photostationary state, fluorescence and optical recording property 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. Using this dithienylethene as optical storage was performed successfully.
