University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

A Liquid Ge(IV) Precursor for Low Temperature Plasma Enhanced Atomic Layer Deposition of Germanium Oxide Thin Films

Small, EarlyView.
Utilizing the 3‐(N,N‐dimethylamino)propyl (DMP) ligand, the new liquid Ge(IV) precursor [Ge(DMP)4] has been developed, which possesses adequate volatility, reactivity, and exceptional thermal stability. This precursor is capable of low‐temperature processing of GeO2 and GeOx with tunable film composition and sub‐nm thickness control in a range from 40 ...

Catalytic Scalable Synthesis of Polyketides Enabled by Chiral Brønsted Acid‐Catalyzed Asymmetric Allylborations

The Chemical Record, EarlyView.
The scalable synthesis of target molecules is crucial for applications such as biological evaluation in medicinal chemistry and even industrial production. We described recent advances in chiral Brønsted acid–catalyzed asymmetric allylboration, which enables access to previously elusive chiral building blocks, and highlight its application to the ...

Inter‐/Intramolecular π‐Stacking in a Benzannulated NCN‐Coordinated Pd(II) Monomer and Dimer Pair: Synthesis, Structure, and Photophysics

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
A cyclometalallated palladium complex and its acetate‐bridged dinuclear analogue, both supported by 1,3‐bis(2‐quinolinyl)benzene ligands, are described. The mononuclear (but not the dinuclear) complex is weakly phosphorescent in the deep red region of the spectrum in solution at room temperature, and both compounds phosphoresce in frozen media at 77 K ...

Exploring Oxygen Electrocatalysis in Phosphonium Ionic Liquids Towards Sodium–Oxygen Batteries

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
Sodium–oxygen (Na–O2) batteries are attractive candidates for high‐energy storage systems; however, their long‐term operation is hindered by the instability of highly reactive intermediates such as the superoxide anion (O2•−). Ionic liquids (ILs) have emerged as promising electrolytes not only because of their intrinsic safety but also due to their ...

Spectroscopic Characterization and Electrocyclic Ring Opening of Parent 2‐Azetine

Journal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.
In this communication we report the observation of 2‐azetine from its N‐Boc‐protected precursor through thermal loss of isobutene and carbon dioxide and its subsequent ring opening to 1‐azabutadienes at elevated temperature. ABSTRACT (N‐Boc)‐protected 2‐azetine serves as a suitable precursor for the generation of parent 2‐azetine.

Organophosphides: A New Class of Luminophore Ligands for Copper(I) Carbene Based TADF Emitters and Photocatalysts

Angewandte Chemie International Edition, Volume 65, Issue 13, 23 March 2026.
Dimesitylphosphide as a heavier congener of established amide ligands for charge‐transfer copper(I) complexes leads to bathochromic shift of the emission by up to 3645 cm−1 into the orange‐red (solid, polymer films) and even NIR (solution). The thermally activated delayed fluorescence exhibits high dissymmetry factors of glum = 10−2 in polystyrene.

Mechanically Triggered Chemical Recyclable Polyethylene‐Like Materials

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Polyethylene‐like copolymers with benchmark properties are prepared by embedding latent cyclobutene mechanophores to overcome PE's end‐of‐life limits. The mechanophores are inert in service but are selectively opened by solvent‐free ball milling to yield well‐defined telechelic oligomers.

Metal‐Free Scission of the NO+ Triple Bond

Angewandte Chemie International Edition, Volume 65, Issue 13, 23 March 2026.
Breaking bonds: The reaction between NO[Al(ORF)4] (RF = C(CF3)3) and the diphosphane PNPtBu (2,6‐bis(di‐tert‐butylphosphino‐methyl)pyridine) leads to the direct and complete cleavage of the NO+ triple bond, one of the strongest chemical bonds known. The mechanism of this reaction was studied using quantum chemical calculations and NMR spectroscopic ...
