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 ...

A pH‐Switchable Triple Hydrogen‐Bonding Motif
ChemistryOpen, 2020 A stimuli responsive linear hydrogen bonding motif, capable of in situ protonation and deprotonation, has been investigated. The interactions of the responsive hydrogen bonding motif with complementary partners were examined through a series of 1H NMR ...

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 ...

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

Chloride ions as integral parts of hydrogen bonded networks in aqueous salt solutions: the appearance of solvent separated anion pairs [PDF]
Physical Chemistry Chemical Physics, 22 (2020) 11038-11044, 2020 Hydrogen bonding to chloride ions has been frequently discussed over the past 5 decades. Still, the possible role of such secondary intermolecular bonding interactions in hydrogen bonded networks has not been investigated in any detail. Here we consider computer models of concentrated aqueous LiCl solutions and compute usual hydrogen bond network ...

Structure of Simple Dipolar Water-Like Fluids: Primitive Model and Hard Tetrahedra
Frontiers in Chemistry, 2021 Dipolar versions of two qualitatively different types of simple short range model fluids which exhibit the phenomenon of hydrogen bonding and which could thus serve as a reference in equations of state for associating fluids have been considered: the ...

Universal features in lifetime distribution of clusters in hydrogen bonding liquids [PDF]
, 2021 Hydrogen bonding liquids, typically water and alcohols, are known to form labile structures (network, chains, etc...), hence the lifetime of such structures is an important microscopic parameter, which can be calculated in computer simulations. Since these cluster entities are mostly statistical in nature, one would expect that, in the short time ...

Intermolecular interactions in a phenol-substituted benzimidazole
Acta Crystallographica Section E: Crystallographic Communications, 2019 Hydrogen bonding plays an important role in the design of solid-state structures and gels with desirable properties. 1-(4-Hydroxybenzyl)-2-(4-hydroxyphenyl)-5,6-dimethyl-1H-benzimidazole was isolated as the acetone disolvate, C22H20N2O2·2C3H6O.
