Synthesis of a Novel Photochromic Diarylethene for Polarization Optical Recording

Article Preview

Abstract:

A novel unsymmetrical photochromic diarylethene compound bearing a benzofuran unit, 1-[2-methyl-5-formyl-3-thienyl]-2-[2-methyl-3-benzofuran-yl]perfluoroyclopentene(1a) have been synthesized, its photochromic, fluorescence and optical strorage properties were investigated. The compound exhibited obviously photochromism both in hexane and in PMMA film. In hexane, the fluorescence intensity of 1a declined along with the photochromism upon irradiation with 297 nm light. The results showed that the cyclization and cycloreversion process of the compound was determined to be the zeroth/first order reaction. This new photochromic system also exhibited remarkable optical storage character.
