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 ...

“Hydridic Hydrogen-Bond Donors” Are Not Hydrogen-Bond Donors [PDF]
Journal of the American Chemical SocietyHerein, we dismiss a recent proposal by Civiš, Hobza, and co-workers to modify the IUPAC definition of hydrogen bonds in order to expand the scope from protonic Y-Hδ+ to hydridic Y-Hδ- hydrogen-bond donor fragments [J. Am. Chem. Soc. 2023, 145, 8550].

A Mechanochromic Hydrogen‐Bonded Rotaxane [PDF]
Macromolecular Rapid Communications, 2020 AbstractTensile forces influence a variety of important biological processes and force sensors are required to study these processes in vivo. Current force sensors are often tailor‐made for a specific application, or activate at much higher forces than those observed at the cellular or tissue level. A versatile force sensor, with tunable mechanical and

Supercritical Water is not Hydrogen Bonded [PDF]
Angewandte Chemie, 2020 AbstractThinking about water is inextricably linked to hydrogen bonds, which are highly directional in character and determine the unique structure of water, in particular its tetrahedral H‐bond network. Here, we assess if this common connotation also holds for supercritical water.

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

Dissimilar diffusion bonding behavior of hydrogenated Ti2AlNb-based and Ti-6Al-4V alloys
Materials & Design, 2018 The effects of hydrogen concentration, heating rate and bonding temperature on dissimilar diffusion bonding of Ti2AlNb-based and Ti-6Al-4V alloys were investigated.

A model for the hydrogen bond [PDF]
Proceedings of the National Academy of Sciences, 1975 A model of the linear hydrogen bond has been devised which is characterized by three physical parameters of the isolated electron donor and proton donor molecules: μ A-H , the bond dipole moment; Δ I , the difference in ionization potential between that

Acta Crystallographica Section E: Crystallographic Communications, 2015 The title carbamate monohydrates, C13H12N2O2·H2O and C12H9BrN2O2·H2O, form isomorphous crystals that are isostructural in their primary hydrogen-bonding modes.

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 ...
