Abstract

The synthesis of three new amido-imine-type hybrid macrocycles based on substituted pyrrole units showed them to act as effective receptors for oxoanions in the solid state and in acetonitrile solution. The acetonitrile solution using standard UV-vis spectroscopic titration methods indicated that the three new receptors display high affinities toward oxoanions with maximal association constants being on the order of [10.sup.7] [M.sup.-1].

2. Synthetic model of the phosphate binding protein: Solid-state structure and solution-phase anion binding properties of a large oligopyrrolic macrocycle

Abstract

The anion templated condensation of dialdehyde and diamine building blocks was used to synthesize the large oligopyrrolic macrocyclic receptors. The X-ray crystal structure of complex revealed anion binding in a 1:1 fashion in the solid state through a complementary hydrogen bond network involving both the receptor and the anions.
