N2 - The complexation of a series of organic buffers by para-sulphonato-calix- [4]-arene has been studied by 1H NMR titration spectroscopy and X-Ray crystallography. The association constant range is observed from 9 mM for 2-[N-Morpholino]ethanesulfonic acid] (MES) to 6720 mM for (1,3- bis[tris(hydroxymethyl)-methylamino]-propane) (BTP). The structure of BTP with para-sulphonato-calix-[4]-arene shows the buffer molecule to be partially included in the host cavity. The packing arrangement shows the normal bilayer organic clay motif.
