Bioinspired Design and Synthesis of Polyphenolic Star‐Like and Hyperbranched Polyester Models

Chemistry – A European Journal, Volume 32, Issue 33, 1 September 2026.
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...

Detection of Testosterone Esters in Urine: Evidence of Trace‐Level Detectability in Doping Control Samples

Drug Testing and Analysis, Volume 18, Issue 9, Page 1157-1162, September 2026.
An ultrasensitive LC‐MS/MS method for detecting testosterone esters (T‐esters) in urine at sub–pg/mL levels is presented. This approach, employing Girard P derivatization, provides the first evidence of T‐esters' trace‐level detectability in human urine.

Synthesis of Sulfonamides in the Biobased Solvent Cyrene

ChemistryOpen, Volume 15, Issue 9, September 2026.
An alternative and efficient protocol for sulfonamide synthesis using the biobased solvent Cyrene is reported. A broad range of amines reacts smoothly with sulfonyl chlorides at room temperature, furnishing 20 sulfonamides in moderate to high yields within 30–60 min. Products are isolated by simple precipitation without chromatography, while Cyrene can

π‐Extended COUPY Fluorophores for Targeted Near‐Infrared Fluorescence and Lifetime Imaging in Live Cells

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
π‐Extended COUPY dyes, obtained by vinylogation of coumarin‐based COUPY scaffolds, shift absorption, and emission deep into the NIR region while preserving compactness and synthetic accessibility. These bright, photostable dyes enable live‐cell imaging, FLIM, and site‐specific peptide conjugation, offering a modular platform for targeted bioimaging and

2‐Vinylpyridine Plasma Polymers as Anion Exchange Membranes in Low Temperature Electrolyzers: Structure‐Property Relationships and Proof of Concept

Plasma Processes and Polymers, Volume 23, Issue 9, September 2026.
2‑vinylpyridine (2VP) plasma polymers were deposited by PECVD and post‐functionalized. Chemically homogeneous films containing vinyl pyridinium groups with competitive ionic conduction were obtained. A water electrolysis cell using a 2VP plasma polymer as an anion‐exchange membrane reached 1 A·cm−2 at 2 V, demonstrating a highly promising proof of ...
