A new photochromic compound 1-(2-ethyl-3-benzothienyl)-2- (2-n-propyl-5-formyl-3-thienyl) perfluorocyclopentene (1a) was synthesized, its photochromic properties were examined, the result indicated that the color of the compound 1a changed from colorless to a blue one upon irradiation with 297 nm UV light, a new absorption maxima were observed at 578 and 587 nm in hexane and PMMA film, respectively. The diarylethene 1a exhibited relatively strong fluorescence in hexane solution and the fluorescence intensity decreased along with the photochromism upon irradiation with 297 nm light. This new photochromic compound also exhibited remarkable holographic optical recording character.
