Abstract

Organic–inorganic composites of (E)-3,5-di(9 H-carbazol-9-yl)-N-(4-(diphenylamino)benzylidene)aniline/dopamine-modified WO₃ (P(TPACz)/WO₃-PDA) were prepared by electrochemical polymerisation. The as-prepared P(TPACz)/WO₃-PDA composites showed good electrochromic and electrochemical performance. The prominent electrochemical performance of P(TPACz)/WO₃-PDA represents a high areal capacitance (32.15 mF cm⁻² at 0.1 mA cm⁻²) and wide range of potential windows (-2.0−1.6 V). Additionally, symmetric supercapacitor devices based on P(TPACz)/WO₃-PDA composite films were successfully constructed, which exhibited a high specific capacitance (13.88 mF cm⁻² at 0.02 mA cm⁻²) and an energy density of 7.71 × 10⁻³ mWh cm⁻² in n-doped station. The remarkable electrochromic and electrochemical performances are due to the synergy between the organic polymer and WO₃-PDA. A complete large-area composite film structure with high conductivity promises fast electronic transport. This study provides a method for preparing multifunctional composite electrode materials, offering technical support for intelligent displays and energy storage technologies.

基于 P(TPACz)/WO3-PDA 纳米复合薄膜的新型电致变色超级电容器装置

通过电化学聚合法制备了(E)-3,5-二(9 H-咔唑-9-基)-N-(4-(二苯基氨基)苯亚甲基)苯胺/多巴胺改性 WO3（P(TPACz)/WO3-PDA）的有机-无机复合材料。制备的 P(TPACz)/WO3-PDA 复合材料具有良好的电致变色和电化学性能。P(TPACz)/WO3-PDA 的突出电化学性能表现为高电容（0.1 mA cm-2 时为 32.15 mF cm-2）和宽电位窗口（-2.0-1.6 V）。此外，还成功构建了基于 P(TPACz)/WO3-PDA 复合薄膜的对称超级电容器器件，在正掺杂电站中表现出较高的比电容（0.02 mA cm-2 时为 13.88 mF cm-2）和 7.71 × 10-3 mWh cm-2 的能量密度。出色的电致变色和电化学性能得益于有机聚合物和 WO3-PDA 之间的协同作用。具有高导电性的完整大面积复合薄膜结构有望实现快速电子传输。这项研究为制备多功能复合电极材料提供了一种方法，为智能显示和储能技术提供了技术支持。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
