thermodynamics of guanidinium and boronicacidinteractions with carboxylates, alpha-hydroxycarboxylates, and diols were studied by determination of the binding constants of a variety of different guests to four different hosts (7-10). Each host contains a different combination of guanidinium groups and boronicacids. The guests included molecules with carboxylate and/or diol moieties, such as citrate, tartrate
