Ion‐Pairing and Counterion Effects in Contemporary Photochemistry

Angewandte Chemie Novit, Volume 2, Issue 2, June 2026.
Ion‐pairing and counterion effects have emerged as fundamental yet underexplored determinants of photochemical behavior. Far from inert, counterions, and Coulombic interactions modulate excited‐state dynamics, quenching efficiencies, emission, and catalytic pathways.

PANI/PTA/Fe3O4 Nanocomposite Coated on Stainless‐Steel Towards Efficient Solid‐Phase Microextraction of Tetracycline From Human Urine Samples Prior to HPLC–DAD Analysis

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Tetracycline (TC) is a commonly prescribed broad‐spectrum antibiotic, and its widespread use together with its persistence in biological matrices, particularly urine, has raised serious concerns related to clinical safety, public health and the emergence of antimicrobial resistance, underscoring the need for its accurate and sensitive ...

Push–Pull Phenazine Fluorophores: Substituent‐Position Effects on Emission and Intermolecular Organization Modulated by Hydrogen Bonding and Molecular Symmetry

ChemistryEurope, Volume 4, Issue 6, June 2026.
Push–pull substitution activates fluorescence in the weakly emissive phenazine scaffold, producing photostable green‐to‐red emitters via a one‐step annulation. A systematic comparison of positional isomers reveals that the Etter‐rule‐directed hydrogen‐bonding patterns modulate the emission wavelength and crystal packing, while the molecular symmetry ...

A Short Synthesis of Cyclo(‐RGDfK) Using a Microflow Reactor

ChemistryEurope, Volume 4, Issue 6, June 2026.
An efficient synthesis of cyclo(‐RGDfK) was achieved by combining a one‐flow three‐component coupling (3CC) reaction via α‐amino acid N‐carboxy anhydrides with rapid macrolactamization using a microflow reactor. Precise control of the water content and base loading in the 3CC reaction enabled the gram‐scale synthesis of the desired tripeptides and ...
