제목 Comparison of Electrochromic devices containing mono-viologen and poly-viologen.  
초록 In this study, we synthesized poly-viologens for application to low-power all-in-one ECDs, tested the effect of Electrochromic, and examined its characteristics. The synthesis of viologen was confirmed by nuclear magnetic resonance (NMR) spectroscopy and electrochemical properties were examined by cyclic voltage measurements (CV) and UV-vis-NIR. ECDs containing poly-viologen have lower color voltages, higher cycle stability, and lower magnetic bleaching based on superior redox reversibility, compared to devices based on mono-viologen. These properties of poly-viologen were able to demonstrate its feasibility as an effective low-power, all-in-one ECD and show that it is a promising candidate for future multifunctional smart features.
