Covalent Organic Frameworks for Neuromorphic Devices

Neuromorphic computing could enablethe potential to break theinherent limitations of conventional von Neumann architectures, whichhas led to widespread research interest in developing novel neuromorphicmemory devices, such as memristors and bioinspired artificial synapticdevices. Covalent organic frameworks (COFs), as crystalline porouspolymers, have tailorable skeletons and pores, providing unique platformsfor the interplay with photons, excitons, electrons, holes, ions,spins, and molecules. Such features encourage the rising researchinterest in COF materials in neuromorphic electronics. To develophigh-performance COF-based neuromorphic memory devices, it is necessaryto comprehensively understand materials, devices, and applications.Therefore, this Perspective focuses on discussing the use of COF materialsfor neuromorphic memory devices in terms of molecular design, thin-filmprocessing, and neuromorphic applications. Finally, we provide anoutlook for future directions and potential applications of COF-basedneuromorphic electronics.
