Nucleobase assemblies supported by uranyl cation coordination and other non-covalent interactions

Non-covalent interactions between proteins and polysaccharides.

Foods with novel or improved properties can be created by utilizing non-covalent interactions between proteins and polysaccharides. In solution, either attractive or repulsive interactions between proteins and polysaccharides can be used to create microstructures that give foods novel textural and sensory properties. At interfaces, attractive electrostatic interactions can be used to create foo...

Single-electron uranyl reduction by a rare-earth cation.

Network Formation via Anion Coordination: Crystal Structures Based on the Interplay of Non-Covalent Interactions.

We describe the synthesis and the structural characterization of new H₂L(CF₃CO₂)₂ (1) and H₂L(Ph₂PO₄)₂ (2) compounds containing the diprotonated form (H₂L2+) of the tetrazine-based molecule 3,6-di(pyridin-4-yl)-1,2,4,5-tetrazine. X-ray diffraction (XRD) analysis of single crystals of these compounds showed that H₂L2+ displays similar binding properties toward both anions when salt bridge intera...

Dissecting the cation-cation interaction between two uranyl units.

We present a state-of-the-art computational study of the uranyl(vi) and uranyl(v) cation-cation interactions (dications) in aqueous solution. Reliable electronic structures of two interacting uranyl(vi) and uranyl(v) subunits as well as those of the uranyl(vi) and uranyl(v) clusters are presented for the first time. Our theoretical study elucidates the impact of cation-cation interactions on ch...

Molecular balances for quantifying non-covalent interactions.

Molecular interactions underlie the whole of chemistry and biology. This tutorial review illustrates the use of rotameric folding molecules, topoisomers, atropoisomers, and tautomers as molecular balances for quantifying non-covalent interactions. This intramolecular approach enables a wide variety of interactions to be examined with a degree of geometric control that is difficult to achieve in...
