Abstract:

A novel unsymmetrical photochromic diarylethene 1-(2-methyl-3-benzofuran)-2-[5-(2-methylbenzene)-2-methyl-3-thieny perfluorocyclopentene 1o was synthesized, then its photochromic, Kinetics and fluorescence properties were investigated. The results showed that the diarylethene compound had good photochromism upon irradiation with 297 nm UV light, in which the absorption maximum were observed at 510 nm in hexane solution and 524 nm in poly methyl methacrylate (PMMA) film. Besides, the cyclization and cycloreversion process of the compound were determined to be the zeroth and first order reaction by UV-Vis spectra, respectively. And, the open-ring isomer of the diarylethene exhibited relatively stronger fluorescence at 427 nm when excited at 273 nm in hexane solution.
