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...
在诸如ferrocene里，两侧的环戊二烯通过pi键与中间的铁离子配位，这就是pi-cation bond。而两侧的环的...

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)...
Combined Cation-pi and Anion-pi Interactions for Zwitterion RecognitionPerraud, ORobert, VGornitzka, HMartinez, ADutasta, J PPerraud O, Robert V, Gornitzka H, Martinez A, Dutasta J-P (2012) Combined cation–π and anion–π interactions for zwitterion recognition. Angew Chem Int Ed 51:...
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...
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 ...
