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

“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].
