Synthesis and Photochromic Properties of Diarylethene 1-2-methyl-5-(4-trifluoromethylphenyl)-3-thienyl-2-2-methyl-5-(3-fluoro-4-chloro)phenyl-3-thienylperfluorocyclopentene

摘要

A new unsymmetrical photochromic diarylethene compound, 1-[2-methyl-5-(4-trifluoromethylphenyl)-3-thienyl]-2-[2-methyl-5-(3-fluoro-4-chloro)phenyl-3-thie nyl]perfluorocyclopentene (1o) was synthesized, and its properties, such as photochromism and fluorescence properties in solution as well as in PMMA amorphous film, were investigated specifically. 1o exhibits good photochromism and fluorescence upon alternating irradiation with UV light and visible light (> 510 nm) in hexane and a PMMA film.
