With the aim of developing electroactive systems capable of electrochemically and specifically recognizing anions [370], some anionic receptors have been bound to redox-active groups such as cobaltocenium, ferrocene, and transition-metal bipyridyl moieties [370-373]. Although such compounds were suitable for the electrochemical recognition of some anionic species in solution, their immobilization on an electrode surface to achieve sensitive layers has been investigated with very few examples.
