Kinetic, electrochemical, and optical storage of a novel diarylethene

A new unsymmetrical photochromic diarylethene compound, [1-(2-methyl-5-phenyl-3-thienyl),2-(2-methyl-5-(2-pyridyl)-3-thienyl)]perfluorocyclopentene (1a), was synthesized and its photochemical properties, such as photochromism and kinetics in solution as well as in PMMA amorphous film, electrochemical properties and optical strorage properties were investigated in detail. The results showed that the cyclization/cycloreversion process of the compound was determined to be the zeroth/first order reaction, the electrochemical properties suggests that the diarylethene derivative can be used as an electrochemical switch and electrochemistry data storage, and the optical propertis can be potential use for data storage.
