Understanding the Interplay Between Thermal Activation, Diffusion, and Phase Segregation of Molecular Dopants Blended with Polymeric Semiconductors

Advanced Electronic Materials, Volume 12, Issue 6, 23 March 2026.
The use of air stable but thermally labile molecules provides an efficient strategy for the N‐type doping of organic semiconductors with relatively low electron affinities. Design criteria for efficient dopants should also take into account diffusion and phase segregation that cannot be decoupled from thermally activated doping.

Aryl Viologen Polymers in High‐Voltage Full‐Organic Batteries

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
A series of aryl‐viologen polymers is synthesized, and their performance in battery half‐cells is investigated. Pairing the best‐performing polymer with a phenothiazine‐polymer positive electrode creates a full‐organic battery with a high discharge voltage of up to 1.8 V and a specific discharge capacity of 78 mAh g−1.

Radical Retrosynthesis of Natural Products Enabled by Iron‐Based Reductive Olefin Coupling

Angewandte Chemie Novit, Volume 2, Issue 1, March 2026.
This review highlights iron‐catalyzed reductive olefin coupling (ROC)—a strategy for C─C bond formation driven by metal‐hydride hydrogen atom transfer (MHAT)—as a key tool in natural products synthesis. This review surveys dozens of total syntheses employing ROC‐based strategies, highlighting its power to forge strained rings, quaternary centers, and ...

Stereoselective β‐C‐aryl Glycosylation Through Ni‐Catalyzed Reductive Cross‐Coupling

ChemistryEurope, Volume 4, Issue 3, March 2026.
A robust Ni‐catalyzed reductive cross‐coupling of glycosyl halides and aryl halides was developed out‐of‐the‐glovebox using air‐stable, bench‐ready Ni(COD)DQ as a source of Ni0. The reaction was applied to a broad substrate scope with excellent β‐stereoselectivity, and the obtained results are supported by mechanistic and density functional theory ...
