A new diarylethenes [1-(2-methyl-1-naphthyl), 2-(2-methyl-5-1,3-dithiolane-3-thienyl)]perfluorocyclopentene 1o based on a hybrid structure of naphthalene and thiophene has been developed. Its properties including photochromism, kinetics and fluorescence were investigated in detail. The results indicated that the compound exhibited good photochromism, which changing from colorless to orange after irradiation with 297 nm UV light both in solution and in PMMA film. The fluorescence switching properties shown the fluorescence spectrum of diarylethene 1o was decreased remarkable along with the cyclization reactions. Finally, using this diarylethene as recording medium, polarization optical recording was carried out successfully.
