The electrochromic (EC) polyamides (Ether-PentiTPA1 and Ether-PentiTPA8) from the electroactive pentiptycene-derived triphenylaminediamine monomers (PentiTPA1 and PentiTPA8) were designed and prepared via polycondensation. The incorporation of rigid and contorted H-shaped pentiptycene scaffolds could restrain polymer chains from close packing and further form intrinsic microporosity in the polymer matrix which could be confirmed by the measurements of WXRD, BET, and PALS. With the existence of intrinsic microporosity, the diffusion rate of counterions between the electroactive polymer film and electrolyte can be promoted during the electrochemical procedure. Therefore, the prepared polyamide Ether-PentiTPA1 exhibits enhanced EC behaviors, such as lower driving potential (1.11 V), smaller redox potential difference ΔE (0.24 V), and shorter switching response time (3.6/5.2 s for coloring/bleaching). Consequently, the formation of intrinsic microporosity can be a useful approach for the enhancement of EC response performance.

基于氧化还原活性芳族二胺的本征多孔聚酰胺的制备与表征

通过缩聚反应设计并制备了由电活性戊烯衍生的三苯胺二胺单体（PentiTPA1和PentiTPA8 ）制成的电致变色 (EC) 聚酰胺（Ether-PentiTPA1和Ether-PentiTPA8 ）。刚性和扭曲的 H 形戊烯支架的结合可以抑制聚合物链的紧密堆积，并进一步在聚合物基质中形成固有的微孔，这可以通过 WXRD、BET 和 PALS 的测量得到证实。由于固有微孔的存在，在电化学过程中可以促进电活性聚合物膜和电解质之间的反离子扩散速率。因此，制备的聚酰胺醚-PentiTPA1表现出增强的 EC 行为，例如较低的驱动电位 (1.11 V)、较小的氧化还原电位差ΔE (0.24 V) 和较短的切换响应时间 (3.6/5.2 s 用于着色/漂白)。因此，固有微孔的形成可能是提高 EC 响应性能的有用方法。
