Supramolecular hierarchy among halogen and hydrogen bond donors in light-induced surface patterning [PDF]

open access: yes, 2015
Halogen bonding, a noncovalent interaction possessing several unique features compared to the more familiar hydrogen bonding, is emerging as a powerful tool in functional materials design.

“Hydridic Hydrogen-Bond Donors” Are Not Hydrogen-Bond Donors [PDF]

open access: yesJournal of the American Chemical Society
Herein, 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].

Two isostructural carbamates: the o-tolyl N-(pyridin-3-yl)carbamate and 2-bromophenyl N-(pyridin-3-yl)carbamate monohydrates

open access: yesActa 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.

Segmented phase of ultraviolet (UV) curable thermoset polyurethanes-graphite (TPU-G) composites [PDF]

open access: yes, 2019
Segmented thermoset polymeric materials properties mainly classified through its carbonyl hydrogen bonding. The addition of graphite particle loading in polymeric materials tailored the functional characteristic of the composites. Therefore, the carbonyl

Hydrogen-bonding interactions in the crystalline-phase structures of cinnamic acid derivatives [PDF]

open access: yes, 1999
Secondary interactions responsible for the crystalline-phase structures of various cinnamic acids and cinnamic acid esters drawn from the Cambridge Structural Database were studied with the help of the Cerius package implemented on an SGI workstation ...

Synthesis of new chiral organosulfur donors with hydrogen bonding functionality and their first charge transfer salts [PDF]

open access: yes, 2013
The syntheses of a range of enantiopure organosulfur donors with hydrogen bonding groups are described including TTF related materials with two, four, six and eight hydroxyl groups and multiple stereogenic centres and a pair of chiral N-substituted BEDT ...

Physics and chemistry of hydrogen in the vacancies of semiconductors [PDF]

open access: yes, 2003
Hydrogen is well known to cause electrical passivation of lattice vacancies in semiconductors. This effect follows from the chemical passivation of the dangling bonds.

Nature of the Hydrogen Bond Enhanced Halogen Bond [PDF]

open access: yesMolecules, 2021
The factors responsible for the enhancement of the halogen bond by an adjacent hydrogen bond have been quantitatively explored by means of state-of-the-art computational methods. It is found that the strength of a halogen bond is enhanced by ca. 3 kcal/mol when the halogen donor simultaneously operates as a halogen bond donor and a hydrogen bond ...

Functional materials based on molecules with hydrogen-bonding ability: applications to drug co-crystals and polymer complexes [PDF]

open access: yesRoyal Society Open Science, 2018
The design, synthesis and property characterization of new functional materials has garnered interest in a variety of fields. Materials that are capable of recognizing and binding with small molecules have applications in sensing, sequestration, delivery
