title: Electrochemically controlled hydrogen bonding. Electrolyte effects in an oxidation-based arylurea-amide system.
abstract: Oxidation of a dimethylaminophenyl-substituted urea leads to a > 2000-fold increase in binding strength between the urea and a diamide guest in 0.1 M NBu4B(C6F5)4/CH2Cl2. The strength of this interaction is obscured when NBu4ClO4 or NBu4PF6 is used as the electrolyte due to competition between the neutral guest and the electrolyte anion for H-bonding to the urea cation.
