Truncated Conjugate Structure Improves Solar‐Driven Hydrogen Peroxide Production Catalyzed by Benzobisthiazole‐Based Conjugated Polymers

Advanced Science, EarlyView.
In this work, a novel molecular design strategy was employed to truncate large‐scale conjugated structures in covalent polymer materials. This approach significantly enhances the catalyst’s light‐harvesting capability, prolongs the lifetime of photogenerated charge carriers, and improves catalytic activity, thereby offering a new conceptual pathway for

Skeletal Editing of Alkenes with Nitroarenes via Photoinduced Rearrangement of N─O═C Dipoles Forms Lactams and Amides

Advanced Science, EarlyView.
Skeletal editing of alkenes via the cascade cleavage of C(sp2)═C(sp2) and C(sp3)─C(sp3) bonds, enabling the insertion of the nitrogen atom and thereby the synthesis of lactam and amide derivatives using nitroarenes as nitrogen atom insertion reagents under light irradiation.

Defect Engineering Activates Pyrene‐Based Covalent Organic Frameworks for Efficient Photocatalytic Uranium Capture

Advanced Science, EarlyView.
A defect‐engineered pyrene‐based covalent organic framework (TP‐PYTO‐SA) is developed via strategic salicylaldehyde incorporation. This approach simultaneously enhances hydrophilicity and introduces uranyl coordination sites, while optimized defect density significantly improves charge separation.

Engineering Active Metal and Nonmetal Sites in Porous Structures of Metal‐Hydroxide Clusters for Enhanced D2/H2 Uptake and Separation

Advanced Science, EarlyView.
Two supramolecular assembly frameworks, constructed from metal‐hydroxide clusters, are synthesized via coordination‐driven self‐assembly mediated by Co2+ and Cu2+ metal centers. One of them demonstrates exceptional D2 and H2 uptake capabilities, achieving the second‐highest uptake capacity for D2.
