Synthesis and Photochromism of 1-(2-methyl-1-benzothiophene)-2-(2-methyl-5-aminomethane-3-thienyl)perfluorocyclopentene

Abstract:

A new unsymmetrical photochromic diarylethene 1-(2-methyl-3-benzothiophene)-2-(2-methyl-5-aminomethane-3-thienyl) perfluorocyclopentene was synthesized and its optoelectronic properties, such as photochromism and the fluorescence spectra of diarylethene 1o in acetonitrile solution was investigated. The compound exhibited good photochromism in solution with alternating irradiation by UV/Vis light, and the maxima absorption of its closed-ring isomer 1c are 530 nm. The open-ring isomer of the diarylethene 1o exhibited relatively strong fluorescence at 375 nm. Its fluorescence intensity decreased along with the photochromism from open-ring isomers to closed-ring isomers upon irradiation with 297 nm UV light.
