Abstract
A new photochchromic diarylethene was synthesized and explored, which is named 1-[2-methyl-5-(2- pyridyl)-3thienyl]-2-[2-methyl-5- 4-bromomethylphenyl -3- thienyl]perfluorocyclopentene. The results showed that it have excellent photochromism, accompanied with the color change from colorless to blue, by photoirradiation in acetonitrile. When irradiated with UV light, the absorbance at 298 nm decreased, while the absorption at 598 nm increased significantly in acetonitrile. In acetonirile, the kinetic experiments showed that the cyclization/cycloreversion process of 1O was determined to be the zeroth/first reaction.
