Synthesis and Properties of 1-(2-methyl-5-chlorine-3-thienyl)-2-(2-ethyl-benzofuran-3-Yl) perfluorocyclopentene and Application

Abstract:

A novel unsymmetrical photochromic diarylethene, 1-(2-methyl-5-chlor-ine-3-thienyl)-2-(2-ethyl-benzofuran-3-yl) perfluorocyclopentene (1a), was synthesized and its photochromism and photo-induced anisotropy was investigated. Specifically, photochromism in solution and in PMMA amorphous films were studied. The diarylethene showed exhibited reversible photochromism, changing from colorless to red after irradiation with UV light both in solution and in PMMA amorphous film. This new photochromic system also exhibited remarkable optical storage character.
