Electrochromism refers to reversible color changes due to electrochemical oxidation or reduction reactions. electrochromic device can be used in smart windows and electronic paper because of their low power consumption. In order to solve the problem of low driving stability of viologen derivatives among various electrochromic substances, substituent was polymerized, and the structure was determined by FT-NMR and FT-IR. In addition, this was fabricated with an electrochromic device and its characteristics were confirmed through UV-vis spectrometer and optical density (OD) measurements. The coloration efficiency increases with the concentration of electrochromic substances, and the longer the chain length, the higher the coloration efficiency. In addition, unlike Ethyl Viologen, Polymer Viologen has more than two multi-color properties and has high driving stability. |
