A new photochromic diarylethene compound [1-(2-methyl-1-naphthyl), 2-(2-methyl-5-1,3-dioxolane-3-thienyl)]perfluorocyclopentene 1o was synthesized and its photochromic properties, kinetic properties and fluorescence switch were investigated in detail. Upon irradiated UV light it changes from colorless to orange and red in solution and PMMA amorphous film, respectively. The kinetic experiment suggested...
A novel photochromic diarylethene compound, 1[2-trifluoromethylphenyl]-2[2-methyl-5-(2-pyridyl)-3-thienyl] perfluorocyclopentene (1o) was synthesized and its photochemical properties, such as photochromism in solution as well as in polymethylmethacrylate (PMMA) amorphous films, fluorescences and photo-mode rewritable recording were investigated. The results showed that the compound exhibits good photochromism...
A unsymmetrical photochromic diarylethene, 1-[2-methyl-5-(2-fluorophenyl)-3-thienyl]-2-(2-cyano-1,5-dimethyl-4-pyrryl)perfluorocyclopentene (lo), was synthesized, and its optoelectronic properties were also investigated. The results showed that this compound exhibited reversible photochromism, changing from colorless to blue after irradiation with UV light both in solution and in PMMA amorphous film...
A new asymmetrical photochromic diarylethene 1-[2-methyl-5-(3-methylphenyl)-3-thienyl]-2[2-methyl-benzofuran-3yl]perfluorocyelopentene (1a) was synthesized and its phtochromic, fluorescence, kinetics and optical recording properties were investigated in detail. This compound exhibited remarkable photochromism, changing from colorless to violet after irradiation with 297 nm UV light both in solution...
A novel photochromic diarylethene, [1-(2,4-dimethyl-5-thiazolyl)-2-(2-methyl-4-(3-methylphenyl)-1-phenyl)] perfluorocyclopentene (1o), has been synthesized. And its photochromic and fluorescent properties were also investigated in detail. The diarylethene showed exhibited reversible photochromism, changing from colorless to yellow after irradiation with UV light in solution. The fluorescence had a...
A novel unsymmetrical diarylethene derivative bearing both thiazole and thiophene moieties, in which a trifluoromethyl group was substituted at the meta-positions of the terminal phenyl ring, was synthesized. At the same time, its photochromic properties and fluorescence switch were investigated in detail. The results showed that this compound exhibited reversible photochromism, undergoing reversible...
