Theranostic Potential of an NAD(P)H‐Activatable Fluorophore: Assessing Cancer Aggressiveness and Triggering Apoptosis

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
DE‐CQ, an NAD(P)H‐activatable theranostic probe, enables the quantification of cancer aggressiveness via glucose‐stimulated fluorescence imaging and selectively induces apoptosis. Its multifaceted efficacy is demonstrated across 2D cells, 3D spheroids, and in vivo models.

Substituent‐Guided Routing in Chemical Reaction Networks

ChemSystemsChem, Volume 8, Issue 6, November 2026.
Substituents act as molecular traffic directors, routing EDC‐fueled oligoesterification either into a constrained reversible dimer loop or through an interconnected, scrambling‐enabled network of higher oligomers. ABSTRACT Metabolism is a complex chemical reaction network (CRN) that distributes reaction flux across multiple pathways, and mimicking such

Structural and Spectroscopic Evidence of Hydrogen Bonded Anionic Wires in Protic Ionic Liquids

ChemPhysChem, Volume 27, Issue 19, 14 October 2026.
Anionic wires of deprotonated carboxylic acids challenge the general wisdom that like charges repel. The hydrogen bond motif observed in the X‐ray structure is even preserved in the liquid state of the material as shown by δ1H NMR spectroscopy. The experimental and theoretical findings provide deep insight into the nature of hydrogen bonding.

Encapsulation of Porphyrins in Polymer Microgels and Microbeads for Heterogeneous Photooxidation

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Amino‐ or ammonium‐functionalized tetraphenylporphyrins were synthesized and encapsulated within polymers to form microgels and microbeads that act as heterogeneous photocatalysts. Photooxidation in aqueous media quantitatively converts sulfides and aldehydes into sulfoxides and carboxylic acids via the singlet‐oxygen pathway, demonstrating an ...

Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

Pyridinium halide promoted ring-opening reactions of exo-norbornene oxide

, 1983
Ring opening of 1 with pyridinium chloride or pyridinium iodide in chloroform and/or pyridine gives significant amounts of halohydrins 2a or 2b, reflecting partial suppression of the Wagner-Meerwein rearrangement that occurs on ring-opening with hydrogen
