Pi-electron stacking stabilizes aromatic rings through electrostatic interactions
Evidence from quantum chemical and materials science studies supports the role of electrostatic interactions in stabilizing pi-electron stacking between aromatic rings.
The retrieved papers include studies (such as [0] and [5]) demonstrating that electrostatic forces and potentials drive and stabilize pi-pi stacking arrangements between aromatic systems, supporting the claim.
