Synthesis, Photochromism Properties of 1-(1,5-Dimethyl-2-Pyrrolecarbonitrile)-2-[2-Methyl-5-(4-Aminomethyl)Phenyl-3-Thienyl] Perfluorocyclopentene

A new unsymmetrical diarylethene derivative 1-(1, 5-dimethyl-2-pyrrolecarbonitrile) -2-[2-methyl-5-(4-aminomethyl) phenyl-3-thienyl] perfluorocyclopentene (1o) was designed and constructed successfully. Its optoelectronic properties have been discussed systematically, such as photochromic, kinetics experiments in acetonitrile solution and PMMA.
