N2 - Tetraalkylammonium salts were found, contrary to literature reports, to be encapsulated into hexameric capsules of pyrogallol[4]arene in benzene solution. The guest affinity depended on the length of the alkyl chain, the counteranion, the solvent used, the ammonium concentration, and most importantly, the pyrogallol[4]arene to ammonium salt ratio. At high ammonium salt to pyrogallol[4]arene ratios no encapsulation was observed, presumably since the high salt destabilized the formed hexamers.
