A novel photochromic diarylethene，1-(3,5-dimethyl-4-isoxazolyl)-2-[2-methyl-5-(10-phenanthrenyl)-3-thienyl]Perfluorocyclopentene was synthesized and its photochromic and fluorescent properties were also investigated. The compound exhibited remarkable photochromism, changing from colorless to pink after irradiation with UV light both in solution and in PMMA film. The fluorescence intensity declined remarkably，when irradiation with UV light. Using this diarylethene 1 as optical storage was performed successfully.
