Synthesis, Photochromism and Fluorescence of a Novel Diarylethene Having Thiazole Unit

Abstract:

A new unsymmetrical isomeric diarylethene was synthesized, namely 1-(2,4-dimethyl-5-thiazolyl)-2-[2-methyl-5- (3-methoxyphenyl)-3-thienyl] perfluorocyclopentene (1o). Its photochromic reactivity both in solution and in PMMA film, photoconversion ratio at photostationary state, and fluorescence were investigated in detail. The compound displayed excellent photochromism both in solution and in PMMA film. The isomeric compound also functioned as a fluorescence switch and concentration dependence on the fluorescence spectrum in hexane.
