摘要

One-dimensional covalent organic frameworks (1D COFs) represent a distinct class of crystalline organic materials featuring linear polymeric chains linked via covalent bonds, offering unique anisotropic properties and tunable functionalities. Despite extensive research on two-dimensional (2D) and three-dimensional (3D) COFs, the structural design, synthesis, and functional exploration of 1D COFs remain less developed. Here, we review recent advances in the rational design principles, including symmetry-matching and topology-guided strategies, alongside synthetic control methods that enable the formation of highly ordered 1D architectures. We highlight their promising applications in photocatalysis, electrocatalysis, optoelectronics, fluorescent sensing, and energy storage, demonstrating enhanced charge transport, catalytic activity, and device performance. These findings underscore the potential of 1D COFs as versatile platforms for next-generation organic functional materials, providing new opportunities for sustainable energy and environmental technologies.
