摘要：

A new unsymmetrical photochromic diarylethene 1o, which is named 1-[2-methyl-5-(4-methoxyphenyl)-3-thienyl]-2-[2-methyl-5-(4-formyphenyl)-3-thienyl]perfluorocyclopentene, was synthesized. Its optical properties, including photochromic reactivity, kinetics and fluorescence properties were investigated in detail. The result indicated that the diarylethene underwent reversible photochromism, changing between colorless and blue in hexane solution and in PMMA, respectively. What is more, the kinetic experiments illustrated that the cyclization/cycloreversion process of this compound was determined to be the zeroth/first reaction. In addition, the results demonstrated that the diarylethene 1o had remarkable fluorescence switching properties.
