2,3-Dimethyl-1H-imidazol-3-ium chloride

IUCrData, 2020
The title salt, C5H9N2+·Cl−, exhibits multiple hydrogen-bonding interactions between the cationic imidazole moiety and the chloride anion. The protonated aromatic nitrogen moiety displays the shortest hydrogen-bonding interactions while weaker hydrogen ...

Disposition of Federally Owned Surpluses [PDF]

, 1944
PDZ domains are scaffolding modules in protein-protein interactions that mediate numerous physiological functions by interacting canonically with the C-terminus or non-canonically with an internal motif of protein ligands. A conserved carboxylate-binding

Hydrogen bonding penalty upon ligand binding.

PLoS ONE, 2011
Ligand binding involves breakage of hydrogen bonds with water molecules and formation of new hydrogen bonds between protein and ligand. In this work, the change of hydrogen bonding energy in the binding process, namely hydrogen bonding penalty, is ...

Triplet–Triplet Energy Transfer Study in Hydrogen Bonding Systems

CHIMIA, 2015
The 2,6-diiodoBodipy–styrylBodipy hydrogen bonding system was prepared to study the effect of hydrogen bonding on the triplet–triplet-energy-transfer (TTET) process. 2,6-DiiodoBodipy linked with N-acetyl-2,6-diaminopyridine (D-2) was used as the

Electrochemical oxidations of thioethers: Modulation of oxidation potential using a hydrogen bonding network

Electrochemistry Communications, 2019
A highly efficient chemo-selective electrochemical oxidation of thioethers to sulfoxides and sulfones was developed. The hydrogen bonding network generated from hexafluoro-2-propanol (HFIP) and acetic acid (AcOH) plays an important role in the modulation
