Enhancement of Electrochromic Switching Properties with Troger's Base-Derived Intrinsic Microporous Polyamide Films

The formation of Troger's Base (TB) configuration is a useful approach to synthesize polymers of intrinsic microporosity (PIM). Herein, the V-shaped TB scaffold is incorporated to prepare electrochromic (EC) polyamide with electroactive triphenylamine (TPA) moiety. The presence of intrinsic microporosity derived from inefficient packing of TB scaffolds can facilitate the counterions diffusion between electroactive species and electrolytes. Consequently, the resulting TB-based polyamide exhibits enhanced EC behaviors, such as a lower driving potential, reduced the difference of redox potentials Delta E, and shorter switching response time compared to the corresponding EC counterpart polyamide.

Automated summary

The formation of Troger's Base configuration is beneficial for synthesizing PIM polymers, and incorporating the V-shaped TB scaffold can enhance the performance of EC polyamide, resulting in lower driving potential and shorter switching response time.
