Photochromic Composite Properties and Application in Optical Memory of a Diarylethene with Benzofuran Unit


Article Preview

A new photochromic diarylethene, 1-[2-methyl-(5-(4- dioxolane)phenyl)-3-thienyl]-2-(2-methyl-3-benzofuran) perfluorocyclopentene (1o), was synthesized and its photochromic and fluorescent properties were investigated.The product has been characterized by elemental analyses, NMR spectrometry, UV/vis spectrophotometry and Fluorescence spectrophotometry. This diarylethene exhibited reversible photochromism and notable fluorescence photoswitches both in solution and in PMMA films, changing from colorless to pink after irradiation with 297 nm UV light.
