Electrocatalytic Polarity Inversion of Azlactones: Access to α‐Quaternary Amino Acids with Electron‐Rich SOMOphiles

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Electrocatalytic polarity inversion of azlactones unlocks their coupling with electron‐rich reaction partners. Triarylamine‐mediated oxidation of the azlactone enolate generates an electrophilic radical intermediate that undergoes selective C4 functionalization with diverse SOMOphiles.

One‐Shot Pd(II)‐Catalyzed Multiple C–H Activation Enables Modular Construction of Fluorenylidene Oxindole‐Based Multi(Polycyclic) Aromatic Enes

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A one‐shot Pd(II)‐catalyzed C─H activation strategy enables the rapid conversion of simple linear propiolamides into structurally diverse mono‐, di‐, and tri‐olefin‐bridged MPAEs. This cascade process orchestrates up to six sequential C–H activations in a single operation, providing streamlined access to highly conjugated architectures.

Mechanistische Diversität in der photoangeregten Radikal‐Redoxchemie: Eine kritische Evaluierung

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Für viele prominente Beispiele der Photoredox‐Katalyse wird angenommen, dass sie über die Anregung einer offenschaligen („open‐shell“) Zwischenform des Katalysators ablaufen. Es wird jedoch intensiv darüber diskutiert, ob solche Mechanismen realistisch sind und, falls ja, wie genau sie ablaufen können.

Enhancement of Dissymmetry Factors Through Axial Elongation of Hetero[n]helicenes

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
A benzofuran scaffolding strategy enables the synthesis of hetero[9]‐, [12]‐, and [15]helicenes. Structural and chiroptical analyses demonstrate that systematic axial elongation increases helical distortion and significantly amplifies luminescence dissymmetry.

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation

Angewandte Chemie International Edition, Volume 65, Issue 42, 12 October 2026.
Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.

Molecularly Templated Buried Interfaces for Inverted Perovskite Solar Cells

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
We demonstrate a molecularly matched buried interface between SAM and perovskite, enhancing adhesion and passivating defects. This optimized interface achieves 26.58% power conversion efficiency and 86.72% fill factor with exceptional operational stability in both large‐area and wide‐bandgap devices, thereby increasing efficiency and prolonging ...

Dopant‐Tailored Matrices: A Crystal Engineering Strategy for Organic Room‐Temperature Phosphorescent Host–Guest Systems and Beyond

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Rather than selecting dopants to match a pre‐existing host matrix, the dopant‐tailored matrix strategy involves rational engineering of host matrices around a preselected class of dopants by targeting matrix packing motifs that promote synergistic host‐dopant interactions upon doping.

Tetracyclic π‐Extended Multi‐Resonant TADF Emitters for Green PSF‐OLEDs With 37.7% EQE and BT.2020‐Compatible Top‐Emitting Devices

Advanced Functional Materials, Volume 36, Issue 79, 1 October 2026.
Ultra‐narrow green multi‐resonance thermally activated delayed fluorescence emitters have been developed by linear π‐extension strategy using tetracyclic naphtho[2,3‐b]benzofuran unit. The resulting phosphorescence‐sensitized OLEDs achieve a maximum external quantum efficiency of 37.7% in the bottom‐emitting architecture, while the complementary top ...

Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...
