Poly(ionic liquid) electrolyte bearing dicationic monomer based on 1,2,3-triazolium for efficient electrochromic displays |
| 초록 |
Herein, we synthesized a poly(ionic liquid) (PIL) exhibiting dicationic monomers based on triazoliums. Alkyne-disubstituted triethylene glycol and azide-disubstituted tetraethylene glycol underwent copper(I) catalyzed azide-alkyne cycloaddition (CuAAC) reaction to produce the new PIL. Activation of the cationic moiety was conducted by quaternizing the triazole group with methyl iodide. Subsequently, quaternized PIL underwent anion metathesis yielding the final material. This unique PIL exhibits very remarkable ionic conductivity which is at par or if not exceeds the best ionenes in literature and exhibits good thermal stability. Hence, an all-solid state electrochromic device (ECD) which efficiently switches from a transparent state to a colored state was fabricated. The development of this ionene with simple structure and excellent physical and thermal properties is promising for the design of no-leak and stable ECDs and other electrochemical devices. |
