Ultra-fast Multicolored Electrochromic Display using Viologen anchored Mesoporous Titania |
| 초록 |
Electrochromic devices (ECDs) have attracted much attention due to their ability to change optical transmittance reversibly through applying an external voltage. Many researchers have been developing EC materials such as metal oxides, small organic molecules, polymers. Among them, Small organic molecules such as viologens are considered promising chromophores due to their capability of providing various colors depending on functional groups. However, viologen based ECDs have poor stability due to dimerization caused by diffusion of molecules. To remove the effect of diffusion, TiO2 template was used to anchor viologens. Herein, we demonstrated ultra-fast multicolored ECDs using viologen anchored mesoporous titania. The fabricated ECDs showed red-green-blue(RGB) colors depending on functional groups of viologens. Moreover, it showed fast switching and high stability. The multicolored ECDs have tremendous potential for applications in full-color electrochromic displays. |
