Synthesis, Properties and Application in Optical Memory of a Photochromic Diarylethene Bearing Fluorine Atoms
A new photochromic diarylethene, 1-(2,4-dimethyl-5-thiazolyl)-2-5-(3,5-difluorophenyl)-2-methyl-3-thienyl perfluorocyclopentene(1a), has been synthesized. its photochromic and fluorescent properties have been investigated in detail. The results showed that this compound exhibited reversible photochromism, changing from colorless to Orange-red after irradiation with UV light both in solution and in PMMA amorphous film. In hexane, the open-ring isomer of the diarylethene 1a exhibited relatively strong fluorescence at 422 nm when excited at 371 nm. The fluorescence intensity decreased along with the photochromism upon irradiation with 297 nm light and its closed-ring isomer showed weak fluorescence. Finally, photo-mode rewritable optical storage using 1a was performed. The images demonstrated that the compound as optical storage material was very sensitive responding to 633 nm recording laser, and the recorded-signals were provided with high S/N ratio.
