Protic Ionic Liquids in Contrast to Aprotic Analogs: Transport Properties and Electrochemical Reactivity

The Chemical Record, EarlyView.
The transport properties and electrochemical reactivity of protic ionic liquids (ILs) are compared with those of aprotic analogs. Protic ILs are characterized by strong cation–anion hydrogen bonding and labile protons, enabling proton conduction and highlighting their potential as fuel cell electrolytes.

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, EarlyView.
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.

Selective photo labeling of tryptophan in N‐acetyl‐L‐tryptophan ethyl ester and peptide WWCNDGR with a diaryl nitrenium ion

Photochemistry and Photobiology, EarlyView.
Visible light photolysis of a N‐(N,N‐diarylaminopyridinium) salt allows for covalent modification of a peptide. Mass spectrometry demonstrates that this procedure selectively labels tryptophan residues. Laser flash photolysis experiments show that bond formation occurs via a diarylnitrenium ion intermediate.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Heart‐Specific Spinal and Vagal Afferents: Transcriptomic Signatures and Optogenetically Modulated Functional Coupling With Cardiomyocytes

Comprehensive Physiology, Volume 16, Issue 4, August 2026.
Selective purification of heart‐specific spinal and vagal sensory neurons by retrograde labeling and FACS purification showed enhanced spontaneous, optogenetic, and chemically stimulated Ca2+ activity. Transcriptomic profiling identified distinct ion channel and GPCR signatures in heart‐specific sensory neurons.

Mitochondria‐Targeting Moieties Based on N‐Tethered Pyridinium Cations

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Pyridinium cations were benchmarked as mitochondria‐targeting moieties in a panel of N‐tethered fluorescent‐, bioactive‐, and inert‐cargo conjugates. 3,5‐Diphenylpyridinium (DPPy+) is a competent triphenylphosphonium (TPP+) surrogate, combining high mitochondria‐targeting efficiency with lower intrinsic effects on mitochondrial function.

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.

Metal‐Free Active Template: A Straightforward Route to 4‐Aminopyridinium‐Based Rotaxane Molecular Shuttles

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Leigh's metal‐free active template‐based SNAr of an amine on halogenopyridiniums, in the presence of a crown ether, successfully afforded 4‐aminopyridinium‐containing rotaxanes. Further molecular machinery was carried out by deprotonation‐then‐carbamoylation of the conjugated amino moiety.

Total Syntheses of Agelamadin F and (±)‐Tauroacidin A, Enabled by NaClO2‐Mediated Coupling Reactions of Oroidin and Amines

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
Total syntheses of agelamadin F and (±)‐tauroacidin A were achieved by sodium chlorite (NaClO2)‐mediated oxidative C─N coupling. Nine C15–N–amino acid‐substituted oroidin derivatives were successfully prepared to demonstrate the applicability and versatility of this oxidative coupling reaction.
