The pore shapes of two-dimensional covalent organic frameworks (2D COFs) significantly limit their practical applications in separation and catalysis. Although various 2D COFs with polygonal pores have been well developed, constructing pentagonal remains an enormous challenge. In this work, we developed one kind the

Abstract Herein, a rational strategy is presented to reduce the energy barrier of singlet ground state excited transitions, whilst simultaneously reducing losses in populating triplet states. The approach relies on constructing 3D space connected donor–acceptor systems COFs. D–A system 8‐connected COFs (denoted as COF‐1 and COF‐2) allows efficient transfer electrons, overcoming traditional electron transport limitations 2D significantly boosting solar utilization efficiency under visible light irradiation. COF‐2, possessing an extended π‐conjugated structure relative COF‐1, demonstrated high selectivity for photocatalytic generation H 2 O (6.93 mmol g −1 h ) natural seawater without need sacrificial reagents, exceeding performance most previously reported COF‐based photocatalysts. this work offers new optimizing photocatalysts production other applications.
