Synthesis, Characterization and Application of Thioindigosulfonic Acids as Electrolytes in an Aqueous Organic Redox Flow Battery

ChemElectroChem, Volume 12, Issue 6, March 15, 2025.
The first synthesis of thioindigosulfonic acids via sulfonation of the parent dye is presented, together with the evaluation of key electrolytic properties, such as solubility and charge transfer characteristics. Investigations conducted in a flow cell demonstrated stable performance over 200 charge/discharge cycles without crossover or degradation ...

Cationic Phosphino Beryllium Scorpionates and their Reactivity as Lewis Acid–Base Pairs

ChemistryEurope, EarlyView.
Monocationic tris(pyrazolyl)borate beryllium phosphine complexes are synthesized and characterized. These compounds readily react with substrates like CO2, SO2, H2, O2, S8, and Se8. Therefore, the nature of the BeP bond is also analyzed computationally. Herein, the article describes a facile and modular access to cationic beryllium phosphine complexes

Recent Advances in Detergent Chemistry and Handling Support Membrane Protein Analysis Including Lipid Interactions

Chemistry – A European Journal, EarlyView.
Detergent design parameters determine experimental successes in membrane protein research. Recent progresses in detergent chemistry are reviewed to promote the top‐down design of non‐ionic detergents for the purification and analysis of intact membrane proteins, including lipid interactions.

Chemical Synthesis of NICOL, A Coligand Secreted Protein Mediating Mammalian Male Reproductive Tract Trans‐luminal Signaling

Chemistry – A European Journal, EarlyView.
NICOL is a small protein engaged the sperm maturation in the epididymis. The recombinant expression of NICOL is low‐yielding and highly heterogeneous, which retards the precise understanding of the function of NICOL. Therefore, we determined the SS pairings and succeeded in the chemical synthesis of highly pure NICOL, which is useful for the structural

Mono‐ IrIII versus Heterobimetallic IrIII‐AuI Complexes for Circularly Polarized Luminescence

Chemistry – A European Journal, EarlyView.
Two enantiopure heterobimetallic complexes, namely Δ‐IrAu‐4 and Λ‐IrAu‐4, have been synthesized. The photophysical and chiroptical properties were characterized and compared with the archetypal Λ/Δ‐Ir(ppy)2(acac), highlighting an increase in gLum value moving from mono‐ to heterobimetallic Ir(III) complexes.

Effective RNA Complexation by [2]Catenanes Confers Enhanced Resistance to Enzymatic Degradation

Chemistry – A European Journal, EarlyView.
Peptide‐based cationic [2]catenanes are resistant to proteases and efficiently complex siRNA, providing protection from degradation by nucleases. Abstract Cationic [2]catenanes bearing l‐arginine residues were synthesized via dynamic covalent self‐assembly in water.

Mass Spectrometric Studies of Reductive Elimination from Si(IV) Anions

Chemistry – A European Journal, EarlyView.
Reductive elimination of ArO─H (Ar = aromatic residue) bonds from pentacoordinate SiIV is characterized by mass spectrometric methods. A Hammet study of substituent effects combined with DFT calculations supports a stepwise mechanism involving a loosely bound aryloxide/hydrosilane ion‐molecule complex as an intermediate. Abstract Reductive elimination (
