title: Evidence of anion-induced dimerization of a squaramide-based host in protic solvents.
abstract: The combination of squaramide units with tetraalkylammonium groups leads two hosts that bind distinctively dianions in water-ethanol mixtures. The formation of complexes of 2:1 stoichiometry with host was supported by ITC, fluorescence, and (1)H NMR data.
