A new photochromic compound 1-[2,5-dimethyl-3-thienyl]-2-[2-methyl-5-pyridine-3-yl-3-thieyl] perfluoroyclopentene(1a) was synthesized, its photochromic properties were examined, the result indicated that the color of the compound 1a changed from colorless to a purple one upon irradiation with 297 nm UV light, a new absorption maxima were observed at 549 and 553 nm in hexane and PMMA film, respectively. The 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.
