Abstract

A new unsymmetrical photochromic diarylethene 1-[2,5-dimethyl-3-thienyl]-2-[2-trifluoromethylphenyl] perfluoroyclopentene(1a) was synthesized, its photochromic properties were examined, the result indicated that the Diarylethene 1a changed the color from colorless to red upon irradiation with 313 nm UV light, in which absorption maxima were observed at 518 and 529 nm in hexane and PMMA film, respectively. The photochromic reaction kinetics indicated that the cyclization processes of 1 belong to the zeroth order reaction and the cycloreversion process belong to the first order reaction. This new photochromic system also exhibited remarkable optical storage character.
