Abstract:
... Herein, three kinds of viologens-based electrochromic devices (ECDs) (heptyl viologen (HV(BF₄)₂), octyl viologen (OV(BF₄)₂), and nonyl viologen (NV(BF₄)₂)) were fabricated utilizing ferrocene (Fc) as a redox mediator. Among them, the NV(BF₄)₂-based ECD exhibits the highest coloration efficiency (36.2 cm²/C) owing to the lowest driving energy. Besides, switching between 0 and 1.2 V, the NV(BF₄)₂-ba ...
