- Abstract
An asymmetrical photochromic diarylethene1-(3,5-Dimethyl-4-isoxazolyl)-2-[2-methyl-5-(5-hydroxymethylpyridyl)-3-thienyl]perfluorocyclopentene (1o) was synthesized and its phtochromic, fluorescent properties were investigated in detail. This compound exhibited remarkable photochromism, upon irradiation with 297 nm UV light, the colorless solution of 1o turned to purple with a new visible absorption band centered at 539 nm ( = 9.01 × 103 L mol-1 cm-1) attributable to the closed-ring isomer 1c. The kinetic experiments showed that the cyclization and cycloreversion processes were zeroth and first order reaction, respectively. Moreover, diarylethene 1o also exhibited obvious fluorescence switch along with the photochromism. The emission intensity of diarylethene 1o in a photostationary state was quenched to ca. 38% in acetonitrilete.
