【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_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...

π-cation应该是指π类阳离子。阳离子-π作用可分为三大类:第一类是简单无机金属阳离子如Na +、K+、 Mg 2 +和Ca 2 +和芳香体系之间的作用;第二类是有机阳离子和芳香体系之间的作用;第三类是分子中带部分正电荷的原子(如N—H键中的氢原子)与芳香体系之间的作用。阳离子与芳香类π体之间...

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)...
