【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...
In this review, we analyze the interaction of ions with aromatic rings from several points of view. We start with a short history of cation and anion interactions and continue with a description of the main forces involved in these interactions. The comprehension of these forces allows us to ...

The sidechain of Arg is more likely than that of Lys to be in a cation-pi interaction. Among the aromatics, a strong bias toward Trp is clear, such that over one-fourth of all tryptophans in the data bank experience an energetically significant cation-pi interaction. 展开 ...
Polarizable potential models for the interaction of Li+, Na+, K+, and NH4+ ions with benzene are parametrized based on ab initio quantum mechanical calculations. The models reproduce the ab initio complexation energies and potential energy surfaces of the cationπ dimers. They also reproduce the ...
Cation-pi interactions in chemistry and biology: A new view of benzene, Phe, Tyr, and Trp. Describes biological structures in which cation-pi interactions are known to be important. Fundamental interaction in gas-phase studies; Benzene's ability ... Dougherty,Dennis,A. - 《Science》 被引量:...
The trends in the BDEs of these alkali metal cation−indole complexes are compared with the analogous benzene and naphthalene complexes to examine the influence of the extended π network and heteroatom on the strength of the cation−π interaction. The Na+ and K+ binding affinities of ...
