Synthesis and binding properties of a new hydrosoluble triphenylene 1b are reported. Selective recognition of acetylcholine (ACh) against other aliphatic ammoniums is achieved by this flat receptor, which also forms complexes with epibatidine and nicotine. Ionic pairing and hydrophobic effects between host 1b and ACh are studied by infrared spectroscopy.
