Abstract
A new calix[4]pyrrole 1 containing a ferrocene moiety attached to one of the meso-positions has been synthesised by co-condensation of pyrrole, cyclohexanone and acetylferrocene. The crystal structure of 1 has been elucidated whilst 1H NMR titration studies in acetonitrile-d3/DMSO-d6 9:1 v/v have revealed that 1 binds fluoride, chloride, and dihydrogen phosphate in this solvent mixture. Electrochemical studies using cyclic voltammetric and square-wave voltammetric techniques show cathodic shifts of up to 100 mV (approx.) with dihydrogen phosphate anions.
