PGSE and NOE NMR evidence for higher order aggregation in some cationic ruthenium complexes in both protic and aprotic solvents [PDF]
, 2003 PGSE and NOE NMR measurements were carried out for complexes [Ru(eta(6)-cymene)((2-R-C6H4)N=C(Me)-C(Me)=N(2-R-C6H4))Cl]X (X=BF4 or BPh4) in both protic and aprotic solvents with a relative permettivity (epsilon(r)) ranging from 2.27 (benzene-d(6)) to 46 ...

Chelation Drives Surface Substitution in Hybrid‐MXenes
Angewandte Chemie, EarlyView.We demonstrate ethylenediamine‐derived bidentate binding on Ti3C2 by controlled deprotonation of ─NH2 groups during reaction with Ti3C2Br2. XRD, XPS, ssNMR, STEM, DFT, and INS confirm the bidentate coordination and the superior stability of chelating modes, while AIMD reveals proton transfer and new surface imine–Ti bonding mode.

Synthesis and fluorosolvatochromism of 3-arylnaphtho[1,2-b]quinolizinium derivatives
Beilstein Journal of Organic Chemistry, 2016 Cationic biaryl derivatives were synthesized by Suzuki–Miyaura coupling of 3-bromonaphtho[1,2-b]quinolizinium bromide with arylboronic acids. The resulting cationic biaryl derivatives exhibit pronounced fluorosolvatochromic properties.

Nucleophilic Gallyl Anions Enable Ga─Au Bimetallic Ammonia Activation
Angewandte Chemie, EarlyView.Unlocking gallyl nucleophiles: Counterion control enables formation of an unsupported gallyl─gold complex. Gold coordination induces a polarity switch at gallium, enabling cooperative activation of NH3 and related N─H/O─H substrates under mild conditions.

Stretchable Energy Storage with Eutectic Gallium Indium Alloy
Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.
