Structure and Spectroscopic Characterisation of Phenanthroline‐Based Iodobismuthate(III) Complexes Utilised for Raw Acoustic Signal Classification

Advanced Intelligent Discovery, Volume 2, Issue 5, October 2026.
Memristors based on trimethylsulfonium (phenanthroline)tetraiodobismuthate have been utilised as a nonlinear node in a delayed feedback reservoir. This system allowed an efficient classification of acoustic signals, namely differentiation of vocalisation of the brushtail possum (Trichosurus vulpecula).

Ionic Liquid Electrolytes for Extreme Temperature Conditions: Challenges and Perspective

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Ionic liquids (ILs) have gained great attention as safe electrolyte components in recent years. This review elucidates the temperature effects on IL‐based electrolytes from molecular configurations, physicochemical properties, and interfacial chemistry, raises the challenges and design strategies operating at low‐ and HT, providing valuable guidance ...

Sulfur‐Bridged Cationic and Neutral [6]Helicenes: Chiral Trityls With Property and Stability Twists

ChemistryEurope, Volume 4, Issue 10, October 2026.
Replacing oxygen or nitrogen bridges with sulfur reshapes cationic [6]helicenes and simultaneously tunes their reactivity, photophysics, and configurational dynamics. Sulfur bridging increases helical curvature and electrophilicity, narrows electronic gaps to promote redshifted absorption and emission with larger Stokes shifts, yet unexpectedly lowers ...

Stereoretentive Nucleophilic Aromatic Substitution Accesses Atropisomeric 4‐Amino‐N‐Arylquinolinium Salts

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Quinolin‐4‐ones were converted to chloroquinolinium salts, allowing formation of axially chiral aminoquinolinium salts via an enantioretentive SNAr reaction with a variety of amine nucleophiles. The salts have a high rotational barrier, with a racemization half‐life of ∼1000s of years.

Nitrooxylation in Organic Synthesis: From Classical Nitrate Ester Formation to Modern Catalytic Strategies

Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.
Nitrooxylation—the installation of nitrate esters (–ONO2) has evolved from classical mixed‐acid protocols to catalytic and mechano‐, flow‐, photo‐, and electrochemical strategies. This review delineates ionic and radical manifolds for C–ONO2 bond formation, emphasizing mechanistic control, selected substrate scope, and selectivity.

Synthesis of Methylisoxazol‐5(4H)‐One Derivatives Using an ʟ‐Proline‐Functionalized‐MMT Catalyst: Molecular Docking and Cancer Cell Line Cytotoxicity Studies

ChemistrySelect, Volume 11, Issue 38, 13 October 2026.
An efficient and sustainable method for the synthesis of biologically relevant isoxazoles is developed using modified montmorillonite‐K10 (MMT) nanoclay as a heterogeneous catalyst. The catalyst exhibited good stability and reusability over five cycles, with minimal loss of activity (95%–88%). ABSTRACT Guided by green chemistry principles, an efficient

Covalent Organic Framework Electrolytes for Solid‐State Lithium Batteries: Designing Ion Highways for Next‐Generation Energy Storage

Small, Volume 22, Issue 55, 1 October 2026.
Covalent organic frameworks provide a structurally programmable platform for solid‐state lithium batteries. This review outlines a design framework linking structural descriptors to ion‐transport metrics. It examines mechanisms of confinement, channel architecture, and hybrid designs, addressing the reasons for the occasional failure of high intrinsic ...
