Paper Abstract

A new photochromic diarylethene bearing thiazole and a six-membered aryl unit 1-(2, 4-dimethyl-5-thiazolyl) -2-(2-methylphenyl)perfluorocyclopentene has been synthesized. Its properties, including photochromism and fluorescence were investigated in detail. It underwent reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light both in solution and in PMMA film. The results showed that this compound exhibited reversible photochromism, changing from colorless to yellow after irradiation with UV light both in solution and in PMMA amorphous film. In hexane, compound 1a exhibited an absorption peak at 293 nm, upon irradiation with 254 nm light, a new visible absorption band centered at 449 nm emerged while the original peak at 293 nm decreased. In PMMA amorphous film, diarylethene 1a also showed good photochromism as similar to that in solution .Upon irradiation with 313 nm light, the absorption maxima was observed at 462 nm. Diarylethene 1 also exhibited good fluorescent switching both in solution and in PMMA flim upon alternating irradiation with UV and visible light. At last, polarization optical recording using diarylethene 1b as recording medium was carried out successfully.
