Porous organic polymers (POPs) with inherent porosity, tunable pore environment, and semiconductive property are ideally suitable for application in various advanced semiconductor-related devices. However, owing to the lack of processability, POPs are usually prepared in powder forms, which limits their application in advanced devices. Herein, we demonstrate an example of information storage application of POPs with film form prepared by an electrochemical method. The growth process of the electropolymerized films in accordance with the Volmer–Weber model was proposed by observation of atomic force microscopy. Given the mechanism of the electron transfer system, we verified and mainly emphasized the importance of porosity and interfacial properties of porous polymer films for memristor. As expected, the as-fabricated memristors exhibit good performance on low turn-on voltage (0.65 ± 0.10 V), reliable data storage, and high on/off current ratio (10⁴). This work offers inspiration for applying POPs in the form of electropolymerized films in various advanced semiconductor-related devices.

使用坚固的电聚合多孔有机聚合物薄膜作为可切换材料的阻变忆阻器

多孔有机聚合物（POP）具有固有的孔隙率、可调节的孔隙环境和半导体特性，非常适合应用于各种先进的半导体相关器件。然而，由于缺乏加工性能，POPs通常以粉末形式制备，这限制了它们在先进设备中的应用。在此，我们展示了通过电化学方法制备的薄膜形式的 POP 的信息存储应用示例。通过原子力显微镜观察，提出了符合 Volmer-Weber 模型的电聚合薄膜的生长过程。考虑到电子传递系统的机理，我们验证并重点强调了多孔聚合物薄膜的孔隙率和界面性能对于忆阻器的重要性。正如预期的那样，所制造的忆阻器在低开启电压（0.65 ± 0.10 V）、可靠的数据存储和高开/关电流比（10 ⁴）方面表现出良好的性能。这项工作为在各种先进半导体相关器件中以电聚合薄膜的形式应用 POP 提供了灵感。
