2018年10月7日 - π - π stacking vs. C-H/ π interaction: Excimer formation and charge resonance stabilization in van der Waals clusters of 9,9'-dimethylfluorene.

In chemistry, pi stacking refers to attractive, noncovalent interactions between aromatic rings, ..... A notable example of applying π–π interactions in supramolecular assembly is the synthesis of catenane. The major challenge for the synthesis of ...

In this paper the role of the peripheral ππ interaction in πN collisions is studied when the momentum of the primary pion is about 7 GeV. It has been shown that ...
