A new unsymmetrical photochromic diarylethene bearing an isoxazole moiety was synthesized and its photochromic and fluorescent properties were also investigated. The compounds exhibited remarkable photochromism both in solution and in PMMA film. In PMMA film, the open-ring isomer of the diarylethene 1 exhibited relatively strong fluorescence at 405 nm when excited at 310 nm. The fluorescence intensity...
A new unsymmetrical photochromic diarylethene, 1-(2,5-dimethyl-3-thienyl)-2-(2-methyl-5-(2,4-difluorophenyl)) perfluorocyclopentene (1a), was synthesized and its optoelectronic properties, such as photochromism in solution as well as in poly-methylmethacrylate (PMMA) amorphous films and fluorescences were investigated. The photochromic reaction kinetics indicated that the cyclization processes of...
A new unsymmetrical photochromic diarylethene 1-[2,5-dimethyl-3-thienyl]-2-[2-trifluoromethylphenyl] perfluoroyclopentene(1a) was synthesized, its photochromic properties were examined, the result indicated that the Diarylethene 1a changed the color from colorless to red upon irradiation with 313 nm UV light, in which absorption maxima were observed at 518 and 529 nm in hexane and PMMA film, respectively...
A novel 2,3-position hybrid diarylethene, 1-(2-methyl-5-phenyl -3-thienyl) -2-(3-methyl-5-phenyl-2-thienyl) perfluorocyclopentene (1 a), was synthesized, and its photochromic reactivity, fluorescent and electrochemical property were also investigated. The results showed that this compound exhibited reversible photochromism, changing from colorless to red after irradiation with UV light both in solution...
