A novel unsymmetrical photochromic diarylethene bearing bisthiophene moiety 1-[2,5-dimethyl-3-thienyl]-2-[2-methyl-5-(2-methylphenyl)-3-thienyl]perfluoroyclopentene (1o) was synthesized and its photochromic, fluorescent and optical storage properties were also investigated. The compounds exhibited remarkable photochromism both in solution and in PMMA film. The result indicated that the diarylethene 1o changed the color from colorless to purple upon irradiation with 297 nm UV light, in which absorption maxima were observed at 527 and 541 nm in hexane and PMMA film, respectively. The open-ring isomer of the diarylethene 1 also exhibited relatively strong fluorescence both in hexane and PMMA film. The fluorescence intensity declined along with the photochromism upon irradiation with 297 nm light. In addition, optical recording using diarylethene 1c as recording medium was carried out successfully.
