Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

Journal of Polymer Science, EarlyView.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

Living Coordination (Co)Polymerization of Norbornene Derivatives by Using Nickel Catalysts Derived From Bis(1,5‐Cyclooctadiene)nickel(0) and 2,6‐Dihydroxybenzoic Acid

Journal of Polymer Science, EarlyView.
The living coordination polymerization of norbornene is achieved using a nickel catalyst derived from Ni(cod)2 and 2,6‐dihydroxybenzoic acid with trityl borate as cocatalyst to produce poly(norbornene) with controllable molecular weights and narrow polydispersity.

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 ...

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.

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 ...

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.
