Oxidation of dimethylaminophenyl-substituted urea leads to a > 2000-fold increase in binding strength between the urea and a diamide guest in 0.1 M NBu(4)B(C(6)F(4))(4)/CH(2)Cl(2). The strength of this interaction is obscured when NBu(4)ClO(4) or NBu(4)F(6) is used as the electrolyte due to competition between the neutral guest and the electrolyte anion for the H-bonding to the urea cation.
