Synthesis, structure and orange‐light emission of a zero‐dimensional antimony(III) halide with the 4,4′‐(ethane‐1,2‐diyl)dipyridin‐1‐ium cation

Acta Crystallographica Section C, Volume 82, Issue 8, Page 453-458, August 2026.
The hybrid halide [H2bpa][SbCl5] [H2bpa is 4,4′‐(ethane‐1,2‐diyl)dipyridin‐1‐ium] exhibits efficient orange emission centred at 600 nm with a photoluminescence quantum yield of 65.57%.Exploring orange‐light‐emitting lead‐free halides with high photoluminescence quantum yields (PLQYs) is a significant challenge in luminescent materials research.

Deep Eutectic Solvent‐Type Mixture as a Green Catalyst in the Solvent‐Free Cycloaddition of CO2 and Epoxides

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
A green, metal‐free catalytic system based on a deep eutectic solvent‐type mixture of tetrabutylammonium iodide and levulinic acid enables the solvent‐free cycloaddition of carbon dioxide (CO2) to epoxides. Cooperative acid–nucleophile activation affords cyclic carbonates in up to 95% yield at atmospheric pressure using only 1.4 mol% of catalyst.

Funktionalisierung von Peptiden auf der festen Phase im späten Synthesestadium

Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Peptidmodifikationen sind für die Kontrolle der Eigenschaften von Peptidwirkstoffen von entscheidender Bedeutung. Daher sind Strategien, die einen effizienten und schnellen Einbau nicht‐kanonischer Modifikationen in Peptide in Parallelformaten ermöglichen, sehr gefragt.

Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
