Study on Photochromic Materials of 1-(2-benzyl)-2-[2-methyl-5-(10-phen-anthrenyl)-3-thienyl]Perfluorocyclopentene

Abstract:

A new unsymmetrical isomeric photochromic diarylethene, 1-[2-methyl-3-benzene]-2-[2-methyl-5-(10-phenanthrenyl)-3-thienyperfluorocyclopentene, was designed and synthesized. Its photochromic and fluorescent properties were also investigated in detail. The compound exhibited excellent photochromism, changing from colorless to orchid after irradiation with UV light both in solution and in PMMA film. Furthermore, the fluorescence intensity of the photochromic diarylethene 1a declined remarkably, when irradiation with UV light. Using this diarylethene 1a as optical storage and fluorescence switches was performed successfully.
