Synthesis and Properties Study of 1â€(2,4â€dimethoxylâ€5†pyrimidinyl)â€2â€[2â€methylâ€5â€(2â€cyanphenyl)â€3â€thienyl] perfluorocyclopentene

Abstract

A novel photochromic diarylethene bearing a sixâ€membered pyrimidine as one aryl moiety was synthesized to investigate its photochromic behaviors. The diarylethene exhibited good photochromism and functioned as a fluorescence switch both in hexane and in PMMA film. The results suggested that the pyrimidine moiety played a vital role during the process of photoisomerization reaction for the diarylethene.
