Organic Frameworks Memristor: An Emerging Candidate for Data Storage, Artificial Synapse, and Neuromorphic Device

Abstract

Memristors have recently become powerful competitors toward artificial synapses and neuromorphic computation, arising from their structural and electrical similarity to biological synapses and neurons. From the diversity of materials, numerous organic and inorganic materials have proven to exhibit great potential in the application of memristors. Herein, this work focuses on a class of memristors based on organic frameworks (OFs) materials, and pay attention to the most advanced experimental demonstrations. First, the typical device structures and memristive switching mechanisms are introduced. Second, the latest progress of OFs‐based memristors is comprehensively summarized, including metal‐organic frameworks (MOFs), covalent organic frameworks (COFs), and hydrogen‐bonded organic frameworks (HOFs), as well as their applications in data storage, artificial synapses, and neuromorphic devices. Finally, the future challenges and prospects of OFs‐based memristors are deeply discussed.

“…It is widely known that synapses constitute most of the functions of neural networks. As the fourth fundamental element, memristors have recently been utilized as artificial synapses and neurons in neuromorphic architectures due to their simplicity and power efficiency and have been found to be a promising candidate for artificial synapses and neurons [12,[22][23][24][25][26][27]. Additionally, more reports have proven that emerging two-dimensional (2D) layered materials are being actively and innovatively used in memristive devices to make a more intelligent electronic synapse [28][29][30][31][32][33].…”

“…In addition, porous crystalline materials have the advantages of a periodic nanoporous crystalline lattice, high specific surface area, and predictable supramolecular structure . Moreover, porous crystalline materials have become popular for the development of synaptic devices due to their exceptional porosity and structure/composition designability. , However, synaptic devices based on porous crystalline materials are still in the research stage due to issues related to robustness and array unit design. In the current research, each method of achieving synaptic functions has inherent drawbacks to some extent, which limits their large-scale application.…”
