Abstract:

A photochromic diarylethene of 1-(2-methyl-1-benzofuran-3-yl)-2-(2-methyl-5-(4-benzylazide)-3-thienyl)) perfluorocyclopentene was synthesized and its properties such as photochromism and fluorescence in solution were investigated in detail. The diarylethene has shown good photochromic behavior in solution with alternating irradiation by UV/vis light. Its fluorescence intensity decreased along with the photochromism from open-ring isomers to closed-ring isomers upon irradiation with 297 nm UV light.
