Rational Design, Synthesis, and Applications of Electron Donor–Acceptor Type Covalent Organic Frameworks for Photocatalysis

Covalent organic frameworks (COFs), featuring rigid π‐conjugated structures, high specific surface areas, open channels, and highly modular characteristics, have become one of the most intensively studied materials in various application fields. The construction strategy of donor–acceptor (D–A) type COFs involves the ordered connection of electron‐donating donor units and electron‐withdrawing acceptor units through specific covalent bonds, ultimately forming a highly ordered alternating D–A network. This article systematically summarizes the design strategies and structural modulation methods of such materials, and outlines their research progress in photocatalytic applications. Finally, the current challenges are analyzed and future prospects are discussed, aiming to provide theoretical guidance and practical insights for the rational design and application of high‐performance D–A COF photocatalysts.
