Abstract Covalent organic frameworks (COFs) have emerged as one of the most studied photocatalysts owing to their adjustable structure and bandgaps. However, there is limited research on regulating light‐harvesting capabilities acceptor building blocks in donor–acceptor (D–A) isomer COFs with different bond orientations. This investigation crucial for elucidating structure‐property‐performance relationship COF photocatalysts. Herein, a series D–A isostructural are synthesized imine orientations using benzothiadiazole its derivatives‐based units. Extended light absorption achieved groups that strong electron‐withdrawing capacities, although this resulted decreased hydrogen generation efficiency. Photocatalytic experiments indicated dialdehyde benzothiadiazole‐based COFs, HIAM‐0015, exhibit highest rate (17.99 mmol g −1 h ), which 15 times higher than isomer. The excellent photocatalytic performance HIAM‐0015 can be attributed fast charge separation migration. work provides insights into rational design synthesis achieve efficient activity.
