A LDH‐Based Supramolecular Photosensitizer‐Functionalized Bioactive Glass Scaffold for Integrated Postoperative Osteosarcoma Recurrence Prevention and Bone Regeneration

Advanced Science, EarlyView.
An intercalation assembly strategy is proposed to construct a novel LDH‐based supramolecular photosensitizer, which exhibits outstanding reactive oxygen species generation activity under 1270 nm laser irradiation. The deposition of supramolecular photosensitizer onto the surface of bioactive glass scaffolds results in the development of an innovative ...

Aminal‐linked Covalent Organic Frameworks for Light Energy Upconversion

Angewandte Chemie, EarlyView.
Aminal‐linked covalent organic frameworks incorporating anthracene units are introduced as solid‐state platforms for triplet–triplet annihilation upconversion. The crystalline materials retain chromophore electronic properties and exhibit fluorescence quantum yields of up to 40%.

Optical Charge Trap Memory Based on Graphene/ZnO Heterostructures for Long‐Term Retention and Adaptive Learning

Advanced Electronic Materials, EarlyView.
A biocompatible graphene/ZnO optical charge trap memory (CTM) is reported with over 54 h retention, enabled by interfacial photodoping. Using transient absorption spectroscopy and electrical analysis, charge transfer quenching is elucidated and reveal that a large energy barrier at the interface is responsible for long‐term memory retention.

Photoinduced Generation of (Boryl)Silyl and (Chloro)Silyl Radicals: Access to Trisubstituted Silylboranes and Chlorosilanes

Angewandte Chemie, EarlyView.
A versatile photoinduced hydro(boryl)silylation and hydro(chloro)silylation of alkenes to construct trisubstituted silylboranes and chlorosilanes was achieved through in situ generation of (boryl)silyl radicals or (chloro)silyl radicals. This mild methodology affords high chemoselectivity and broad functional group tolerance to enable direct access to ...

A rational strategy to optimize photodrugs by Molecular Dynamics simulations for killing drug‐resistant Gram‐negative bacteria

AIChE Journal, EarlyView.
Abstract Antimicrobial resistance has become a major threat to human health, particularly for Gram‐negative bacteria such as Acinetobacter baumannii and Klebsiella pneumoniae. Disruption of membrane integrity is regarded as a promising antimicrobial strategy that does not induce distinct drug resistance, while increasing the internalization of drug ...

Out‐of‐Equilibrium Supramolecular Assembly Sustained by Photocatalysis

Angewandte Chemie, EarlyView.
Catalysis sustains structure: A Pt(II) supramolecular photocatalyst persists in a far‐from‐equilibrium state only as long as it remains photocatalytically active. Without ongoing catalytic activity, the system irreversibly relaxes into a thermodynamically stable but inactive state (PtB). Catalysis is essential for sustaining its structure.
