Paper Abstract

A new photochromic diarylethene compound, 1-[2-methyl-5-(3-methoxylphenyl)-3-thienyl]-2-[2-methyl-5-(3- trifluoromethylphenyl)-3-thienyl]perfluorocyclopentene (1a), was synthesized and its photochromism and photo-induced anisotropy was investigated. It showed good photochromism both in solution and PMMA amorphous film by photoirradiation. In hexane, the colorless solution turned to blue with a new broad absorption band centered at 579 nm upon irradiation with 254 nm UV light. The blue colored solution returned to colorless upon irradiation with visible light (λ > 500 nm). The open-ring isomer of 1a exhibited relatively strong fluorescence at 352 nm when excited at 295 nm in hexane. In PMMA film, diarylethene 1a also showed good photochromism. In addition, the result indicated that the compound showed a photoinduced anisotropic phenomenon accompanying the photochromic reaction, which illustrated that the diarylethene can be potentially used as polarization multiplexed image recording medium.
