Synthesis and Application of 1-[2-methyl-3-benzofuran]-2-[2-methyl-5-(4-pentylphenyl)-3-thienyl]perfluorocyclopentene

Abstract:

An unsymmetrical photochromic diarylethene 1o, which is named 1-[2-methyl-3-benzofuran]-2-[2-methyl-5-(4-pentylphenyl)-3-thienyl] perfluorocyclopentene, has been synthesized, and its properties including photochromism and fluorescence have been investigated. The compound exhibited remarkable photochromism, changing from colorless to light pink after irradiation with 297 nm UV light. The photochromic reaction kinetics was studied in solution and their cyclization/cycloreversion processes belong to zeroth/first order reaction in acetonitrile.
