Paper Title:
Photochromism of a New Unsymmetrical Diarylethene Bearing both Thiazole and a Methoxyl Group
  Abstract

A new unsymmetrical isomeric diarylethene bearing an electron-donating methoxyl group at ortho-positions of the terminal phenyl ring was synthesized, namely 1-(2,4-dimethyl-5-thiazolyl) -2-[2-methyl-5-(2-methoxyphenyl)-3-thienyl]perfluorocyclopentene (1o). The compound displayed excellent photochromism both in solution and in PMMA film. The isomeric compound also functioned as a fluorescence switch by photoirradiation in solution. In addition, cyclic voltammetry tests showed that the electron-donating methoxyl group at the terminal benzene ring had a significant effect on the electrochemical properties of the isomeric diarylethene.
