Association constants for the reaction between a fourfold hydrogenbond receptor 4 possessing an AADA hydrogenbond pattern and several complementary partners 5–7 with DDAD and DDA patterns have been determined by NMR titration and by isothermal titration calorimetry (ITC). A variation of one donor site in the DDAD pattern resulted in the following, surprising sequence of stability of the complexes:
