Super‐Electron‐Donor Polymers: From Monomer Design to Redox Functionality
Small, EarlyView.2,2'‐Bipyridinylidenes are known for their “super‐electron‐donor” properties and have therefore been used beyond the field of organic synthesis. Their two‐electron redox process at a low potential of 1.8 V vs. Li/Li+ makes them attractive negative p‐type electrode‐active materials.

Small, EarlyView.1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Oxaziridines: Versatile Reagents in Modern Organic Synthesis
The Chemical Record, EarlyView.Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes
Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species

Catching Wyckoff’s Phantom: The Peculiar Crystal Structure of Orthorhombic Cs[ICl2]
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Over 100 years after the first crystallographic elucidation, the still elusive orthorhombic modification of Cs[ICl2] could be isolated and structurally elucidated from the reaction of aqueous H[ICl4] with Cs2CO3. The [ICl2]− anion shows an unusually large bond length asymmetry, which shows characteristics of a Cl−∙∙∙I–Cl complex with an extremely ...
