A new unsymmetrical isomeric photochromic diarylethene, 1-[2-methyl-3-benzothiophen-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 medium violetred after irradiation with UV light both in solution and in PMMA film. Furthermore, the fluorescence intensity of the photochromic diarylethene1adeclined remarkably, when irradiation with UV light. Using this diarylethene 1a as optical storage and fluorescence switches was performed successfully.

A novel unsymmetrical photochromic diarylethene, 1-[2-methyl-5-(3,5-difluorophenyl)- 3-thienyl]-2-(2-methyl-5-formyl-3-thienyl) perfluorocyclopentene (1) has been synthesized. Its photochromic and properties have been investigated in detail. Specifically, photochromism in solution and in polymethylmethacrylate (PMMA) amorphous films were studied. The results showed that this compound exhibited reversible photochromism, changing from colorless to blue after irradiation with UV light both in solution and in PMMA amorphous film. The photochromic reaction kinetics indicated that the cyclization processes of 1 belong to the zeroth order reaction and the cycloreversion process belong to the first order reaction. In addition, photomode rewritable optical storage using 1b was performed. The images demonstrated that the compound can be used as optical storage material.
