Memristors Based on Metal–Organic Frameworks: Synthesis, Mechanism, Categories, and Future

Abstract

Metal–organic frameworks (MOFs), as organic–inorganic hybrid materials, possess the advantages of both the flexibility and functional diversity of organic materials and the high stability and mechanical properties of inorganic materials. They have a rich and diverse framework and pore structures that can be designed and tailored, high chemical and thermal stability, and flexibility. MOFs can be widely used in fields such as nonvolatile memory, neural morphology computing, and flexible wearable devices. This Perspective summarizes the research progress of memristive devices using MOF materials as functional layers in recent years. Moreover, it elaborately expounds on the challenges encountered and opportunities presented to them. This review mainly introduces the synthesis methods of MOF materials and the common resistance switching mechanisms of such resistive devices. Based on the classification of metal nodes in MOFs, we discuss the performance, advantages, and potential applications of MOF-based resistive devices and put forward the future development direction of this field.
