pi-pi stacking interaction4',7-dimethoxylisoflavone, C17H14O4, (I), is linked into a supramolecular structure by a variety of weak but direction-specific intermolecular forces, the molecules are linked into chains through C-H center dot center dot center dot O hydrogen bonds, thes...
The triptycene-based macrocycle was initially situated on the MtA station due to intercomponent hydrogen bonding and π−π stacking interaction between methyltriazolium and anthracene units. However, after adding four equivalents of K+, the macrocycle toggled to the AQ station due to π−π ...
Comprehensive exploration of the unique intermolecular interactions and pi-pi stacking characteristics of cyclo[18]carbon 文/Sobereva@北京科音2020-Oct-3 1 前言 18碳环(cyclo[18]carbon)是18个碳组成的环状体系,是近期最热门的分子,它具有与一般化学体系截然不同的几何结构、电子结构和各种性质。在2019年于凝...
解释机理时，大家都提到pi-pi stacking, pi-pi 电子给体受体interaction, pi -pi interaction之类的。

In this work we report the first example of a trinuclear Pt(II) complex with Pt-Pt-Pt bonds that are not facilitated by direct intervention of bridging ligands but are partially held by the attractive -stacking interaction between the units of the 4,4'-dimethyl-2,2'-ligands. The effect ...
We demonstrate that a single amino acid substitution, F84T, akin to the H84T mutation and predicted to remove the pi–pi stacking interaction, does indeed decrease mitogenicity while preserving antiviral activity. F84T still maintains some mitogenic activity, but it stimulates peripheral blood ...
