Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Main‐chain polyfullerenes: Taking fullerene to the next dimension

Polymer International, EarlyView.
This short review appraises main‐chain polyfullerenes. Their slow development over 30 years has suddenly boomed with a rapid growth due to exciting developments in solar energy. Abstract This mini‐review gives an overview of the development, chemistry, properties and applications of main‐chain polyfullerenes.

Phospholipids of Clostridium butyricum. IV. Analysis of the positional isomers of monounsaturated and cyclopropane fatty acids and alk-1′-enyl ethers by capillary column chromatography

Journal of Lipid Research, 1971
The positional isomers of the cyclopropane fatty acids of Clostridium butyricum phospholipids have been analyzed by capillary column gas–liquid chromatography. Greater than 95% of the methylenehexadecanoic acids was the 9,10 isomer. On the other hand, 60–

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Creating a Masterpiece. The Road to (and Beyond) Woodward and Hoffmann's 1969 Angewandte Chemie Treatise

The Chemical Record, EarlyView.
This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.

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

Journal 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.

Main Group Metals in Redox Catalysis

European Journal of Inorganic Chemistry, Volume 29, Issue 22, 1 August 2026.
Main group metal redox catalysis is emerging as a credible alternative to transition metal chemistry. Elements from groups 13 to 15 now enable diverse catalytic manifolds, driven by ligand design and control of electronic structure. This review highlights recent advances, key design principles, and remaining challenges, positioning main group metals as
