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.

Beyond Integer Charge Transfer: A New Design Rule Linking Dopant Strength and Counterion Separation to Efficient Carrier Transport in Conjugated Polymers

Small, EarlyView.
In this Research Article, the authors introduce a new design principle for doped conjugated polymers, showing that dopant energy depth relative to the host polymer (ΔE) can be leveraged to minimize Coulomb interactions and boost conductivity. This discovery offers a new and simple strategy to optimize the performance of organic electronics for everyday

Hydrogen Bonding Denticity Governs Surface Modulation in Inorganic Perovskite Nanocrystals

Small, EarlyView.
Organic cations with distinct hydrogen‐bonding denticities enable systematic modulation of perovskite nanocrystal surfaces. Increasing denticity from mono‐dentate MA+ to bi‐dentate FA+ and multi‐dentate GA+ strengthens interactions with surface iodides, effectively suppressing surface defects.

Direct Synthesis of Short‐Chain Alkylammonium Capped FAPbI3 Perovskite Nanocubes for High‐Efficiency Solar Cells

Small, EarlyView.
Direct injection synthesis with short‐chain decylammonium iodide produces uniform FAPbI3 perovskite nanocubes through isotropic growth and surface passivation. The resulting films show reduced defect‐mediated recombination, improved phase stability, and efficient charge transport.

Advances in research on layered double hydroxides for biomedical applications

Smart Molecules, EarlyView.
Layered double hydroxides (LDHs) are pH‐responsive nanomaterials with broad biomedical applications. This review summarizes LDH synthesis methods and compares their advantages. It highlights LDHs' progress in cancer therapy, including chemo‐photothermal, chemo‐immunotherapy, and photodynamic‐immunotherapy combinations and their potential in bone repair.

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Bi[IrBi6I12], Ag3[IrBi6I12], and BixCu3–3x[IrBi6I12]: Rock‐Salt Superstructures Based on Heavy‐Atom Clusters

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Analysis of lattice changes and weak interactions in a series of solvatomorphic isostructural spin‐crossover compounds

Acta Crystallographica Section C, EarlyView.
Five new solvatomorphic spin‐crossover compounds were crystallized and structurally characterized. Variable‐temperature X‐ray diffraction, Hirshfeld surface analysis and NCI plots shed light on the role of weak interactions.Five new solvate forms of the complex bis(thiocyanato‐κN)[tris(pyridin‐2‐ylmethyl)amine‐κ4N,N′,N′′,N′′′]iron(II), [Fe(NCS)2 ...

Syphilis and ‘Sons of Empire’: The ‘Prostitute’ and Britain's Fighting Arm in Nineteenth ̵ Century Colonial Punjab

Gender &History, EarlyView.
ABSTRACT The British army in India took great care to provide European troops with facilities for sexual relations while anxiously managing venereal disease. Examining archival evidence, political debates and medical discourse from the nineteenth century, this article examines the colonial military enterprise of regulated prostitution in colonial ...
