Outside Back Cover: Fused‐Ring Acceptor–π–Acceptor Architecture Enables Near‐Infrared‐Absorbing Mesoporous Covalent Organic Frameworks for Enhanced H 2 O 2 Photosynthesis

Fused-ring acceptor–π–acceptor COFs are rationally designed and synthesized. They possess mesoporous crystalline frameworks with planar geometry, extended long-range electron delocalization and near-infrared light absorption. Such synergistic structural and optoelectronic merits greatly boost the separation and migration of photogenerated charge carriers, delivering an excellent photocatalytic H2O2 production rate of 6.8 mmol g−1 h−1 without sacrificial agents.
