摘要：

New mono- and bis-substituted amide-linked aza crown ether-cobalticinium compounds have been prepared and shown by H-1 nuclear magnetic resonance and electrochemical studies to accept chloride and bromide guest anions. Preliminary association constant determinations suggest that use of aza-crown-ether-complexed sodium cations in combination with an amide-linked positively charged cobalticinium redox centre leads to cooperative enhancement of the strength of anion complexation.
