Abstract

New porphyrin-based anion receptors have been prepared from meso-tetrakis(pentafluorophenyl)porphyrin (TPPF20) and diamine derivatives. These receptors (compounds 1–3) interact preferentially with phosphate anions both in organic solutions and in basic aqueous media when coated on gold piezoelectric quartz crystals. A single crystal X-ray structure of the bis-HF complex of a imine derivative of 1 was obtained; it serves to highlight the main interactions between the anion and cation receptors in the solid state.
