Phosphine-mediated hydrogen bond and phosphorescence energy transfer for tunable chiroptical afterglow in stacked polymers [PDF]
Nature CommunicationsPolymer-doped chiral organic afterglow (COA) materials represent an emerging frontier in photonics, yet their development is constrained by weak hydrogen bond interactions and limited spectral diversity.

Study on the turn structure of polypeptides containing glycine and L-proline
Journal of Hebei University of Science and Technology, 2016 The formation of turn structure in peptide chains has direct relations with intramolecular hydrogen bonds, therefore the existence of this bond can be tested to research the turn structure.

A Spectroscopic Overview of Intramolecular Hydrogen Bonds of NH…O,S,N Type
Molecules, 2021 Intramolecular NH…O,S,N interactions in non-tautomeric systems are reviewed in a broad range of compounds covering a variety of NH donors and hydrogen bond acceptors. 1H chemical shifts of NH donors are good tools to study intramolecular hydrogen bonding.
