1D-COFs: A precision “structure–function” design platform for advanced memristors and energy storage

As a novel class of crystalline porous materials, one-dimensional covalent organic frameworks (1D-COFs) have shown significant promise for electronic devices and energy storage, owing to their unique double-chain edge structures that enhance electronic conjugation and reduce energy loss. This paper systematically reviews the synthesis strategies, structural characteristics, and structure-property correlations, as well as the cutting-edge applications of 1D-COFs in electronic devices (e.g., memristive and flexible devices) and energy storage systems (e.g., metal-ion batteries). It also analyzes current challenges and outlines future research directions.
