Electronic Modulation of K⁺‐Intercalated Polymeric Carbon Nitride via ─C≡N/─OH Functionalization for Efficient Photocatalytic H2O2 Production

Advanced Science, EarlyView.
K+ is successfully embedded in the PCN interlayers via a high‐temperature polymerization. The incorporation of K+ perturbs the local electronic structure via interaction with nitrogen lone pairs, narrowing the PCN bandgap, which exhibits superior photocatalytic performance, achieving a high H2O2 generation rate both in situ and under sunlight ...

Unsupervised Hierarchical Symbolic Regression for Interpretable Property Modeling in Complex Multi‐Variable Systems

Advanced Science, EarlyView.
UHSR translates complex chemical behavior into clear and explainable equations. Applied to thin‐layer chromatography, it automatically uncovers the mathematical rules linking a molecule's structure to its polarity. This approach matches the accuracy of advanced AI while providing interpretable results, earning greater trust from chemists. The method is

Spatial Control Over Tether‐Tunable Coordination on Palladium for Divergent Synthesis of Bicyclo[n.1.0]alkanes via Oxidative Cyclopropanation of Enynes

Advanced Science, EarlyView.
We have developed a Pd‐catalyzed oxidative cyclopropanation of 1,n‐enynes employing cyclic diacyl peroxides as bifunctional reagents that serve as both tether‐tunable oxidants and spatially controlled dicarboxylate anions. ABSTRACT Bicyclo[n.1.0]alkanes are highly valuable scaffolds in drug discovery and synthetic chemistry.

Site‐Selective Ligand Selection by Mutational Profiling for Covalent RNA Targeting

Angewandte Chemie, EarlyView.
Using a mutational profiling approach an RNA‐targeted covalent probe was developed that is highly selective for the FMN riboswitch. The covalency was further supported by mass spectrometry experiments. The covalent probe selectively modifies the riboswitch at low micromolar concentrations within 10 min and remains functional when applied to an entire ...
