摘要：

Receptors based on guanidinium- and pyrrole-containing binding sites were designed and synthesized for selective recognition of orthophosphate in aqueous solution. Various analytical techniques were used to understand solution behavior and anion binding properties of the receptors in methanol and methanol/water mixtures. Binding studies revealed that the structure of pyrrole-containing binding sites has great influence on selectivity of receptors for orthophosphate. The receptor with bulky substituents in the meso-position of the dipyrrolylmethane core demonstrated the highest selectivity for orthophosphate over other inorganic anions.
