Five unsymmetrical diarylethenes with a naphthalene moiety were synthesized, and the structures of four diarylethenes were determined by single crystal X-ray diffraction analysis. The naphthalene was connected directly to the central perfluorocyclopentene

Three unsymmetrical isomeric diarylethenes bearing an electron-withdrawing cyano group were synthesized and their structures determined using single-crystal X-ray diffraction analysis. Each of the compounds displayed excellent photochromism in solution, in PMMA film, as well as in the crystalline phase. The isomeric compounds also functioned as a fluorescence switch in PMMA films. The cyclization quantum yield and the absorption maxima of both the ring-opened and ring-closed isomers increased in the order: ortho- a marked effect on the electrochemical behaviours of these isomeric diarylethenes.
