1H-NMR as a structural and analytical tool of intra- and intermolecular hydrogen bonds of phenol-containing natural products and model compounds.
Pantelis Charisiadis,Vassiliki G. Kontogianni,Constantinos G. Tsiafoulis,Andreas G. Tzakos,Michael G. Siskos,Ioannis P. Gerothanassis +5 more
TL;DR: The use of the high resolution phenol hydroxyl group 1H-NMR spectral region provides a general method for the analysis of complex plant extracts without the need for the isolation of the individual components.

Curcumin amorphous solid dispersions: the influence of intra and intermolecular bonding on physical stability
TL;DR: Overall, polymers proved to be crystallization inhibitors, but inhibition was limited due to the intramolecular hydrogen bonding in curcumin, which leads to a decrease in the ability of the polymers to interact at a molecular level.

Applications of guanine quartets in nanotechnology and chemical biology
Loic Stefan,David Monchaud +1 more
TL;DR: This Review describes the production of such functional suprastructures and their applications in nanotechnology, soft matter and chemical biology, and demonstrates how these multidisciplinary investigations cast a bright light on the diversity that guanines, synthetic Guanines and related nucleobases uniquely offer in terms of both structure and function.

DPT tautomerization of the long A∙A Watson-Crick base pair formed by the amino and imino tautomers of adenine: combined QM and QTAIM investigation.
Ol’ha O. Brovarets’,Ol’ha O. Brovarets’,Roman O. Zhurakivsky,Dmytro M. Hovorun,Dmytro M. Hovorun +4 more
TL;DR: It was shown for the first time that the biologically important A�’A* base pair formed by the amino and imino tautomers of adenine (A) tautomerizes via asynchronous concerted double proton transfer (DPT) through a transition state (TS), which is the A+∙A− zwitterion with the separated charge, with Cs symmetry.

Hydrogen bond design principles.
TL;DR: This overview features a discussion relating molecular structure to hydrogen bond strengths, highlighting the following electronic effects on hydrogen bonding: electronegativity, steric effects, electrostatic effects, π‐conjugation, and network cooperativity.
