Abstract

In this work, novel di-ureasil hybrid materials doped with three room-temperature ionic liquids (RTILs) (1-methylimidazolium chloride ([MIm]Cl), 1-ethyl-3-methylimidazolium chloride ([EMIm]Cl), and 1-butyl-3-methylimidazolium chloride ([BMIm]Cl)) are synthesized by the sol-gel method, and their potential as ormolytes in electrochromic devices (ECDs) is evaluated. The ECDs developed exhibit high visible and near-infrared (NIR) transparency, fast switching times, and good coloration efficiency and memory effect, allowing us to foresee their application in energy-efficient smart electrochromic windows.
