چکیده
A novel photochromic diarylethene bearing a pyrimidine moiety, 1-(2,4-dimethoxyl-5-pyrimidinyl)-2-[2methyl-5-(3-methyl)-3-thienyl]perfluorocyclopentene has been synthesized. Its properties, including photochromic and fluorescent behaviors, have been investigated. The compound exhibited remarkable photochromism, changing from colorless to red after irradiation with UV light in solution. The cyclization/cycloreversion process of the compound was determined to be the zeroth/first order reaction. The results indicated that the pyrimidine moiety played a very important role during the process of photoisomerization reactions. Keywords-diarylethene; photochromism; pyrimidine; fluorescence

متن کاملDensity Functional Theory Study of Photodegradation and Fatigue-Resistance of Photochromic Materials for Optical Switching and Data Storage Applications
Photochromic compounds are promising materials for optoelectronic and photonic applications because of their ability to undergo change in color under UV/Vis illumination due to reversible chemical transition from open to closed ring isomers (photocyclization). The by-produc formation may lead to irreversible photodegradation of the material, called fatigue. We use Density Functional Theory meth...
