Electrochromic devices (ECDs) can reversibly change their optical properties via redox reactions of EC materials, which is triggered by applying external voltages. One of the most crucial factors for practical uses is a high operating stability. In this work, the performance of ion gel-based ECDs was investigated with varying molecular structures (symmetric di-heptyl viologen and asymmetric mono-heptyl viologen) and the concentration of EC materials. Based on the results, we successfully demonstrated ECDs having highly stable long-term coloration/bleaching cyclic stability with a high purity magenta color. |
