摘要：
An asymmetrical photochromic diarylethene1-(2-Methyl-3-benzothiophene)-2-[2-methyl-5-(3-cyanophenyl)-3-thienyl]perfluorocyclopentene (1o) was synthesized and its phtochromic, fluorescent properties in both solution and PMMA films were investigated in detail. This compound exhibited remarkable photochromism, upon irradiation with 297 nm UV light, the colorless solution of 1o turned to violet with a new visible absorption band centered at 535 nm (epsilon = 1.08 x 10(4) L mol(-1) cm(-1)) attributable to the closed-ring isomer 1c. The emission intensity of diarylethene 1o in a photostationary state was quenched to ca. 32% in hexane and 43% in PMMA film.
