Abstract

A new unsymmetrical photochromic diarylethene 1-[2-cyano-1, 5-dimethyl-4-pyrryl] -2-[2-methyl-5-(1, 3-dioxolane)-3-thienyl] perfluorocyclopentene has been synthesized, and its properties including photochromism, kinetics and fluorescence have been investigated in detail. The results showed that its photochromic behaviors could be modulated by UV/Vis light, changing from colorless to blue in acetonitrile solution.
