Article Preview

A novel photochromic diarylethene based on thiophene and a six-membered aryl moieties 1-[(2-methyl-5-(p-methylphenyl)-3-thienyl)]-2-[(2-trifluoromethylphenyl)]perfluorocyclopentene(1a) has been synthesized. Its properties, including photochromic behavior and fluorescent properties, have been investigated. The results showed that this compound exhibited reversible photochromism, changing from colorless to purple after irradiation with UV light both in solution and in PMMA amorphous film. The fluorescence intensity decreased along with the increase of solution concentration. The diarylethene exhibited relatively strong fluorescence at different solvent.
