This review presents an overview of the recent advancements in covalent organic framework (COF)-based memristors, organized into four representative categories: imine-linked, vinylene-linked, amide-linked, and boronate ester-linked COFs. The discussion systematically examines how the unique bonding structures of each type influence their performance in memory storage, logic operations, and sensory detection applications.

Covalent organic framework (COF)-based memristors are promising for novel storage and neuromorphic computing applications. The ordered porous structure, tunable chemical composition, and exceptional stability of COFs offer an ideal material foundation for the development of high-performance memristors. This review summarizes a classification method for COFs based on their distinctive bonding patterns, with particular emphasis on the key developmental milestones and functional applications of imine, amide, boronic ester, and vinylene-based architectures. Lastly, a thorough discussion of the future challenges and prospects associated with COF-based memristors is provided.
