A photochromic diarylethene 1,2-bis(2-methyl-5-(2,2'-dicyanovinyl)- thien-3-yl)perfluorocyclopentene (1a) was synthesized. Its photochromic properties in different solution and PMMA film were investigated. While, fluorescence properties in different solution has also been discussed. The results of the research demonstrate that it has shown good photochromic behavior and relatively strong fluorescence in different solution at room temperature. At last, the dynamics of photochromic ring-opening and ring-closure reaction in different solvent was also elucidated. The result indicated that its cyclization/cycloreversion process was determined to be zeroth/first order reaction in different solution, respectively.
