Nettet16. sep. 2011 · These interactions include π-stacking (see picture), XH/π, cation/π, and anion/π interactions. Abstract Non-covalent interactions with aromatic rings pervade modern chemical research. The strength and orientation of these interactions can be tuned and controlled through substituent effects. Nettet6. des. 2024 · 12.4 Aromatic-Polar Interactions Aromatic rings can in principle interact with any polar moiety [69, 70, 308]. We will consider different classes of polar interactions. The most familiar will be a type of hydrogen bond, in which the face of the aromatic ring forms the acceptor of a hydrogen bond.
