摘要：
1-[2-methyl-5-(3-fluorophenyl)-3-thienyl]-2-[2-methyl-5-(3-fluoro-4-chloro)phenyl-3-thienyl] perfluorocyclopentene (1o) as a new photochromic diarylethene has been synthesized. Their properties, including photochromic reactivity, fluorescence and electrochemical properties were investigated and, it's a reaction kinetics were investigated, it have good photochromism both in PMMA film and in solution with alternating irradiation by UV/Vis light, Upon irradiation with 297 nm light, the colorless solution of compound 1 turns blue, while the blue solution becomes colorless after irradiated with visible light (lambda>510 nm). The product has been characterized by Fluorescence spectrophotometry, UV/vis spectrophotometry. The cyclization processes of compound (1o) belong to the zero order reaction.
