摘要

The photochromic diarylethene, 1,2-bis[2-methyl-5-(3-trifluoromethylphenyl)-3-thienyl]perfluorocyclopentene(BMTTP), was synthesized and its photochromic kinetics, fluorescence and X-ray structure were investigated. This compound underwent a photochromic reaction both in solution and the single crystalline phase. Its cyclization/cycloreversion process was determined to be zeroth/first order reaction, respectively, and this is the first report on the cyclization/cycloreversion reaction order. In addition, its fluorescence property was also discussed.
