Lone pair-aromatic interactions: To stabilize or not to stabilize
Article Abstract:
Empirical and theoretical methods are applied to demonstrate the capacity of aromatic rings to act as acceptors in hydrogen bonds and lp***pi interactions in crystal structures of DNA, RNA, and proteins are analyzed to evaluate their energies. It is observed that interactions are usual in nucleic acids and that important binding energies occur only when the aromatic systems are positively polarized.

Bioinspired hydrogen bond motifs in ligand design: The role of noncovalent interactions in metal ion medicated activation of dioxygen
Article Abstract:
The work on 3d transition metal complexes with rigid H-bond frameworks and their reactivity with dioxygen is described. It is found that to duplicate the features of molecular architecture in synthetic systems, urea-based ligands are developed that creates rigid organic frameworks when bonded to metal ions.
