Synthesis and Photochromism studies of 1-(2,4-dimethoxyl-5-pyrimidinyl)-2-2-methyl-5-(3-trifluoromethylpheny). 3-thienylperfluorocyclopentene

摘要

The photochchromic diarylethene was synthesized and explored, which is named l-(2,4-dimethoxyl-5-pyrimidinyl)-2-[2-methyl-5-(2-trifluoromethylphenyl)-3-thienyl]perfluorocycl opentene. This compound has shown good photochromic behavior. When irradiated with UV light. The compound changed from colorless to violet, which showed a relatively strong fluorescence switch along with the photochromism from open-ring isomer to closed-ring isomer.
