A new unsymmetrical photochromic diarylethene compound, 1-[(2-methyl-5-(4-dioxolane-phenyl)-3-thienyl)]-2-(5-cyano-1,5-dimethyl-4-pyrryl)perfluorocyclopentene (1o), was synthesized and its photochemical, fluorescence properties were investigated in detail both in solution and PMMA amorphous film. The results showed that the compound exhibited remarkable photochromism, changing from colorless to violet after irradiation with 297 nm UV light. Finally, using this diarylethene as recording medium, polarization optical recording was carried out successfully.
