An electroactive polyazomethine was prepared directly on a transparent electrode by the polycondensation of bis(triphenylamine) dialdehyde and its complementary methoxytriphenylamine diamine. The method of coating the electrode for preparing electrochromic layers could be upscaled to prepare working devices larger than standard test devices. The film prepared by thermally annealing the complementary monomers was both electroactive and switched its color with an applied potential. The yellow electrochromic polyazomethine could be electrochemically oxidized reversibly to obtain a blue film. The electrochromic test device fabricated from the polyazomethine was operated upwards of 1 h for performance assessment. The electrochromic response times of the electrochromic device were ca. 3.3 and 1.2 s for the coloration and bleaching, respectively. The upscaled device prepared by the straightforward coating approach had consistent metrics with the small-area test device.
通过双（三苯胺）二醛与其互补的甲氧基三苯胺二胺的缩聚反应，直接在透明电极上制备了一种电活性聚甲亚胺。用于制备电致变色层的电极涂覆方法可以扩大规模，以制备比标准测试装置更大的工作装置。通过对互补单体进行热退火制备的薄膜具有电活性，并且在施加电势时会改变颜色。黄色的电致变色聚甲亚胺可以通过电化学可逆氧化得到蓝色薄膜。由聚甲亚胺制成的电致变色测试装置运行超过1小时以进行性能评估。该电致变色装置的电致变色响应时间分别约为3.3秒（着色）和1.2秒（褪色）。通过直接涂覆方法制备的扩大规模的装置与小面积测试装置具有一致的指标。
