Synthesis and Property of 1-(2,4-dimethoxyl-5-pyrimidinyl)-2-2-methyl-5-(2-fluorophenyl)-3-thienyl perfluorocyclopentene

摘要

A novel photochromic diarylethene based on pyrimidine moiety was synthesized. Its properties, including photochromism and fluorescence were investigated in detail. The compound exhibited remarkable photochromism, changing from colorless to red after irradiation with UV light. The fluorescence had a remarkable initial increase with subsequent dramatic decrease with increasing concentration. The results indicated that the pyrimidine moiety played a very important role during the process of photochromic reaction for the diarylethene derivative.
