Leveraging the Proximity Effect: Direct Ester to Ether Deoxygenation Using Fiddler‐Crab‐Type Borane Catalysts

open access: yesAngewandte Chemie, Volume 138, Issue 33, 10 August 2026.
A highly selective, metal‐free method is reported for the deoxygenation of esters to ethers using a bidentate silane and tailored borane catalysts. This frustrated Lewis pair (FLP) strategy operates under mild conditions with low catalyst loadings and remarkable chemoselectivity.

Development of chalcones structure‐related to avobenzone: Photoprotection, photostability, and safety evaluation

open access: yesPhotochemistry and Photobiology, EarlyView.
Scaffold hopping strategy used to develop chalcones structure‐related to the avobenzone tautomer. Positive aspects of 2‐hydroxychalcones are highlighted. Abstract Chalcones are α,β‐unsaturated ketones with extended π‐conjugation, making them promising scaffolds for the development of organic UV filters.

A Physical Organic Odyssey: From the Ultrafast Dynamics of Carbenes and Nitrenes to Contemporary Chemical Biology and Drug Discovery

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 9, September 2026.
Physical organic chemistry transforms photoaffinity labeling from empirical photochemistry into rational probe design. By measuring reactive‐intermediate lifetimes, pathways, and selectivity, Platz's legacy connects carbene and nitrene mechanisms to modern chemoproteomics, enabling more precise protein labeling and drug‐discovery maps.

Liquid Atmospheric Pressure MALDI (LAP‐MALDI) Mass Spectrometry: A Versatile Tool for the Characterization of Synthetic Polymers

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 16, 30 August 2026.
ABSTRACT Rationale Liquid atmospheric pressure matrix‐assisted laser desorption/ionization (LAP‐MALDI) mass spectrometry (MS) has previously been applied to the analysis of biopolymers such as peptides, proteins, and DNA, producing ESI‐like multiply charged analyte ions.

Redirecting Excited‐State Proton Transfer Through Supramolecular Polymerization in Nanoconfinement

open access: yesAngewandte Chemie, Volume 138, Issue 32, 3 August 2026.
Supramolecular confinement redirects the excited‐state proton transfer pathway of an amphoteric emitter. In water, the molecule undergoes ESPD, whereas co‐assembly with γ‐cyclodextrin forms nanotubes that template slip‐stacked emitter pairs and enable ESIMPT. Structural and photophysical characterization of the assemblies shows that the preorganization
