【3.4.6.2】Cation–pi interaction(阳离子-π相互作用) 阳离子-π相互作用是富电子π系统(例如苯,乙烯,乙炔)和相邻阳离子(例如Li +,Na +)之间的非共价分子相互作用。 这种相互作用是单极(阳离子)和四极(π系统)之间非共价键的一个例子。 结合能非常重要,固溶相值(solution-phase values)与氢键和盐桥在同一数...

Cation–pi interactionComplexationCalixarenes are widely used molecular scaffolds that have found broad application in supramolecular chemistry. Generally, binding interactions between calixarenes and cations involve the phenolic oxygen atoms as donor groups. In principle, however, the arenes could stabilize...
Cation-pi_interactionCation-pi_interactionis a between the face of an electron-rich (e.g. , , ) and an adjacent (e.g. Li, Na). This interaction is an example of noncovalent bonding between a monopole (cation) and a (π system). Bonding energies are significant, with solution-phase va...
Energetically, cation-p interactions are comparable to or stronger than either a typical hydrogen bond or interaction between ion pairs (salt bridge) and thus make a significant contribution to the recognition and binding of ligands to their receptors and can be valuable when predicting drug-receptor...

The stabilization energy originates in part from electrostatic attraction between the cation, and regions of high electron density in pi-orbitals of the aromatic group, leading to the name cation-pi interaction. The lysine and tyrosine containing peptide, N-acetyl-Pro-Pro-Lys-Tyr-Asp-Lys-NH(2)...
Cation-pi interaction - a key force for sorption of fluoroquinolone antibiotics on pyrogenic carbonaceous materials. Cation-pi attraction is a major force that determines macromolecular structures and drug-receptor interactions. However, the role of the cation-pi interaction in sorption of amino ...
