Abstract
A new unsymmetrical photochromic diarylethene 1-[2-cyanophenyl]-2-[(2-methyl-5-(4- methoxyphenyl)-3-thienyl)]perfluorocyclopentene (<b>1a</b>) was synthesized, its photochromic properties were examined, the result indicated that the Diarylethene <b>1a</b> changed the color from colorless to purple upon irradiation with 297 nm UV light, in which absorption maxima were observed at 550 and 557 nm in hexane and PMMA film, respectively. This new photochromic system also exhibited remarkable fluorescence switching in hexane solution and remarkable optical storage character in PMMA film.
