Nucleophilic Aromatic Substitution in the Gas Phase

open access: yesJournal of Physical Organic Chemistry, Volume 39, Issue 11, November 2026.
In this review, we highlight experimental studies of gas‐phase SNAr. Studying reactions in the gas phase provides invaluable information on intrinsic reactivity by eliminating the complications of solvent effects. Because SNAr is a fundamental reaction in chemical research and organic synthesis, understanding its underlying reactivity and mechanisms is

Evaluating a river's ecological health: A multidimensional approach

open access: yesEnvironmental Science and Ecotechnology
Evaluating the health of river surface water is essential, as rivers support significant biological resources and serve as vital drinking water sources. While the Water Quality Index (WQI) is commonly employed to evaluate surface water quality, it fails ...

VOCs Adsorption and Exchange Properties in Bispidine‐Based Mn(II) 1D CPs Made of Orthogonally Oriented Linear Chains

open access: yesChemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Combining the chiral bispidine ligand L1 with MnCl2 affords coordination polymers (CPs) with an unusual topology for this family of compounds, consisting of orthogonally packed ribbon‐like one‐dimensional (1D) chains. Their behavior was investigated through single‐crystal‐to‐single‐crystal exchange with aromatic volatile organic compounds (VOCs) and ...

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

open access: yesAdvanced Functional Materials, Volume 36, Issue 87, 29 October 2026.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...
