Synthesis and Characterization of Unsymmetrical Diarylethene Based on Phenylpentane

Article Preview

Abstract:

An unsymmetrical photochromic diarylethene, 1-[2-methyl-3-benzothiophene]-2-[2-methyl-5-(4-pentylphenyl)-3-thienyl] perfluorocyclopentene (1a), has been synthesized, and its properties including photochromism and fluorescence have been investigated. The results showed that this compound undergo reversible cyclization and cycloreversion reactions upon alternating irradiation with UV and visible light in solution.
