Abstract

A new water-soluble polyanionic dendrimer containing 81 benzoate termini (diameter: 11 ± 1 nm from DOSY NMR spectroscopy) has been synthesized; it interacts with acetylcholine cations in water-soluble assemblies in which each carboxylate terminus reversibly forms contact ion pairs and aggregates at the tether termini, as shown by 1H NMR spectroscopy.
