摘要：
A new unsymmetrical photochromic diarylethene, 1-(2,4-dimethoxy-5-pyrimidinyl)2-(2-methyl-5-pyridine-3-thienyl)perfluoroncyclopentene (la) was synthesized and its photochemical and fluorescent properties were inverstigated. The measurement results demonstrated that the compound had good photochromism in hexane solution upon irradiation with 297 nm UV light. And the cyclization process of the compound were determined to be the zeroth order reaction by UV-Vis spectra. Besides, the open-ring isomer of the diarylethene exhibited relatively stronger fluorescence at 406 urn when excited at 289 nm in hexane solution.
