Synthesis, Photochromism and Optical Storage of a New Type of Diarylethene Compound

Article Preview

Abstract:

A new unsymmetrical photochromic diarylethene 1-(2-methylbenzothiophene-3-yl)-2-(2-nbutyl-5-(2,2′-dicyanovinyl)thiophene-3-yl)perfluoroncyclopen-tene (1a), was synthesized and its optoelectronic properties, such as photochromism in solution as well as in poly-methylmethacrylate (PMMA) amorphous films, and the fluorescence spectra of diarylethene 1a was investigated. The photochromic reaction kinetics indicated that the cyclization process of 1a belongs to the zeroth order reaction and the cycloreversion process belongs to the first order reaction. The diarylethene can be potentially used as holographic optical recording medium.
