A new asymmetrical photochromic diarylethene, 1-(2-methyl-3-benzofuryl)-2-(2-methyl-5-naphthyl-3-thienyl)perfluorocyclopentene (1o) was synthesized, and its photochromism and fluorescence properties were studied in detail. Upon irradiation with 297 nm UV light, the colorless 1o changed to violet both in solution and solid state. In addition, 1o had favourable fatigue resistant, which could be potential use for practical application in optical devices. Finally, a remarkable fluorescence switching was observed along with the photocyclization reaction of 1o.
