High-performance electrochromic device based on ambipolar system of polyamides and viologen exhibits extremely high absorption over the visible and near-infrared (NIR) regions, indicating the device could be changed from highly transparent to truly black. This electrochromic device implies high potential of application as shutter for transparent displays and energy-saving devices.
