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

open access: yesAdvanced 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 Charge Heterogeneity in COF/Graphene Hydrogels for Salt‐Resistant Solar Evaporation

open access: yesAdvanced Science, EarlyView.
Hetero‐charged COF/graphene hydrogel (HCG‐1) with spatially separated cationic and anionic domains is engineered to achieve salt‐resistant solar evaporation. This unique charge architecture regulates Na⁺ and Cl− distribution, promotes intermediate‐water formation and effectively suppresses salt crystallization, enabling stable solar evaporation in ...

Stereoselective Ferrier‐Type O‐Glycosylation Enabled by Difluoromethylated Glycal Donors

open access: yesAdvanced Science, EarlyView.
A fluorine‐mediated stereoselective Ferrier‐type glycosylation is reported. Glycals are pre‐decorated with photo‐2‐difluoroalkylation and reacted with diverse acceptors to obtain exclusively α‐selective Ferrier rearrangement products. Abstract The effective construction of structurally homogeneous glycosides is requisite in oligosaccharide assembly and
