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 new photochromic diarylethene compound 1-(2, 4-dimethyl-thiazole-5-yl)-2-[2-methyl-5-(2-trifluorophenyl)-3-thien yl]perfluorocyclopentene (1a) was synthesized and its photochromic properties, fluorescence switch and polarization optical recording were investigated in detail. The diarylethene 1a showed excellent photochromic properties upon UV or visible light irradiation, which changed the color...
A novel photochromic diarylethene, 1-(2-ethyl-3-benzothienyl)-2-(2-trifluoromethylphenyl)perfluorocyclopentene (1a), was synthesized and its photochromic and fluorescent properties were investigated. The compound underwent reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light both in solution and in PMMA film. And the absorption maximum of compound...
