摘要：

New mono- and bis-urea substituted ferrocene receptors have been synthesised. Proton NMR anion coordination studies with chloride and dihydrogen phosphate reveal the presence of bulky tert-butyl ester group urea substitiuents disfavours H2PO4- complexation and amplifies the recognition of Cl-. Electrochemical studies showed these urea ferrocene receptors electrochemically recognise H2PO4- and Cl- and AcO- via perturbations of the respective ferrocene oxidation wave.
