Study on photochromic properties of 1-(2-methoxyphenyl)-2- 2-methyl-5-(1, 3-dioxolane)-3-thienylperfluorocyclopentene

摘要

A new unsymmetrical photochromic diarylethene 1o, which is named 1-(2- methoxyphenyl)-2-[2-methyl-5-(1, 3-dioxolane)-3-thienyl]perfluorocyclopentene, was synthesized. Its photochromic and simulated molecule structure were also investigated in detail. This diarylethene underwent reversible photochromism, changing between colorless and blue in hexane solution upon appropriate irradiation with UV/vis light. The kinetic experiments illustrated that the cyclization/cycloreversion process of this compound was determined to be the zeroth/first reaction. In addition, this compound can be used as optical recording materials.
