Porous polymeric covalent organic frameworks (COFs) have been under intense synthetic investigation with over 100 unique structural motifs known. In order to realize the true potential of these materials, converting the powders into thin films with strict control of thickness and morphology is necessary and accomplished through techniques including interfacial synthesis, chemical exfoliation and mechanical delamination. Recent progress in the construction and tailored properties of thin film COFs are highlighted in this review, addressing mechanical properties as well as application-focused properties in filtration, electronics, sensors, electrochemistry, magnetics, optoelectronics and beyond. Additionally, heterogeneous integration of these thin films with other inorganic and organic materials is discussed, revealing exciting opportunities to integrate COF thin films with other state of the art material and device systems.

共价有机骨架薄膜和异质结构的合成和定制特性

多孔聚合物共价有机框架 (COF) 一直在进行深入的合成研究，已知有 100 多种独特的结构基序。为了发挥这些材料的真正潜力，有必要将粉末转化为严格控制厚度和形貌的薄膜，并通过界面合成、化学剥离和机械分层等技术来实现。本综述重点介绍了薄膜 COF 的构造和定制特性的最新进展，涉及机械特性以及过滤、电子、传感器、电化学、磁学、光电子学等领域的以应用为中心的特性。此外，还讨论了这些薄膜与其他无机和有机材料的异质集成，揭示了将 COF 薄膜与其他最先进的材料和器件系统集成的令人兴奋的机会。
