Abstract
A new photochromic diarylethene compound 1-[2-methyl-3-thienyl]-2-[3, 5-dimethyl-4-isoxazolyl]perfluorocyclopentene (1o), was synthesized and its photochromic and fluorescent properties were investigated. Diarylethene 1o changed the color from colorless to orange upon irraditation with 297 nm UV light, which the absorption maxima were observed at 486 nm in hexane solution. This new photochromic system also showed remarkable fluorescence switching in the solid state. Finally, rewritable optical storage using 1o was performed. The results demonstrated that the compound was very sensitive responding to 633 nm recording laser.
