Hydrogen‐Bonded Molecular Clusters Transform into Surface‐Passivated Fluorophores in Carbon Nanodots: Mechanistic Insight and Sensing Application Toward Bilirubin and Cu2+ Ions

ChemPhysChem, Volume 27, Issue 9, 14 May 2026.
The present study demonstrates the transformation of dual‐emissive H‐bonded molecular clusters of fluorophores into single emissive amorphous carbon nanodots and their structure‐property relationship in fluorescence‐based sensing of Bilirubin and Cu2+ ions. The present study aims to explore the origin of fluorescence in nitrogen‐doped carbon dots (NCDs)

Electrochemical Cascade N‐Acylation and C–H Halogenation of Azaindoles

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
Substituted azaindoles are valuable yet synthetically challenging scaffolds. Here, we report an electrochemical cascade strategy that combines N‐acylation with electro‐induced C–H halogenation in a single, atom‐economical process. This additive‐free method enables efficient synthesis of halogenated N‐acyl azaindole amides and carbamates from readily ...

Confined‐Assembled FeNi Alloy‐Embedded Porous Carbon Nanosheet Reactors as Efficient Bifunctional Electrocatalysts for Rechargeable Zinc‐Air Batteries

Battery Energy, Volume 5, Issue 3, May 2026.
Through ZnO‐templated localized assembly, a branched network was constructed with in‐situ grown carbon nanotubes and abundant mesopores formed upon template removal, yielding a hierarchical structure combining high surface area with efficient mass transport.

Contemporary Applications of Chemical Libraries for Drug Discovery and Methods for Their Synthesis

ChemistryEurope, Volume 4, Issue 5, May 2026.
Screening of chemical libraries has over the past decades become a cornerstone of drug discovery. Today, a broad range of chemical libraries exist but they are often not well described in terms of diversity. This review describes current efforts which aim to visualize chemical diversity in compound collections and discuss current trends in synthetic ...

Quantifying Carboxylate Burial in Synthetic Hydrophobic Pockets in Water

ChemistryEurope, Volume 4, Issue 5, May 2026.
How “buried” is a buried ion? Double mutant cycles quantify the cost of placing a carboxylate within a deep aromatic calix[4]pyrrole pocket in water. The penalty is only +1.3 to +3.0 kcal·mol−1 because water penetrates through cracks and the portal, creating a wet, high‐dielectric microenvironment.
