Abstract
The neurotransmitter acetylcholine (ACh) is bound with 50-micromolar affinity by a completely synthetic receptor (host) comprising primarily aromatic rings. The host provided an overall hydrophobic binding site, but one that could recognize the positive charge of the quaternary ammonium group of ACh through a stabilizing interaction with the electron-rich π systems of the aromatic rings (cation-π interaction). Similar interactions may be involved in biological recognition of ACh and other choline derivatives.
