Two redox anion receptors based on calix[4]pyrrole and ferrocene have been synthesized. The electrochemical investigation revealed that these compounds can be response to the anions with different shifts of Fc/Fc(1) couple. With the H-1 NMR titration study, the selectivity to F and AcO ions in CD3CN Solution was confirmed. The conformations of the mono-aromatic meso-substituted calix[4]pyrroles, which were the synthetical intermediate of the ferrocene based receptors, and their anion complexes in the solid state have also been Studied by single X-ray crystallography. and the rationality of the crystal conformations was proved by theoretical study.
