Synthesis and Property of a New Diarylethene Bearing both an Isoxazole Moiety and a Chlorine Atom
A new photochromic diarylethene 1-(3,5-dimethyl-4-isoxazolyl)-2-[2-methyl-5- (3-chlorophenyl)-3-thienyl]perfluorocyclopentene (1o) has been synthesized. Its properties, including photochromism and fluorescence were investigated in detail. It underwent reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light both in hexane and in PMMA. The results showed that this compound exhibited reversible photochromism and good fluorescent switching after irradiation with UV light and visible light.
