Viologen -tethered imidazole based poly(ionic liquid) for single molecule electrochromic device application |
| 초록 |
The progress in the research aiming to reduces the heating/cooling load and save energy in buildings has led to the development of electrochromic ‘smart windows’ which can regulate solar energy. This new class of single molecule PIL was synthesized by methylation reaction with N-methyldiethanalamine and functionalized with imidazole ring then center N atom functionalized with 4,6-dibromoviologen further polymerized with AIBN polymer. This new material exhibits electrochromic property suitable for devices such as smart windows. Its electrochemical property was analyzed by cyclic voltammetry and amperometry. Its physical and thermal stability were examined by thermogravimetric analyses. Its performance was evaluated by sandwiching the new electrochromic material between two indium-tin oxide (ITO) glass. This electroactive material showed excellent electrochemical and physical and thermal stability. It also showed remarkable color switching performance. |
