cation complexation, although a multitude of new structures and properties may be expected in view of the role played by anionic species in chemical as well as in biological processes.' For instance, macropolycyclic ammonium salts yield katapinates2 and anion cryptate~;,-~ polyguanidinium and polyammonium salts act as anion complex one^;^^^ quaternary ammonium salts allow selective extraction and transport

protonated, for anions. The protonation constants of compounds 1–4 have been determined. They are high enough for compounds 1–4 to be fully protonated in a pH-range close to neutrality, as required for binding of anions of weak acids. The effect of structural features on the protonation constants are briefly discussed in relation to the design of macrocyclicpolyamine ligands.
