Abstract

This review focuses on supramolecular receptors designed for the detection of guest species in solution by virtue of their incorporation of a redox-active group, which is able to electrochemically respond to a binding event. The redox-active group is normally covalently attached in close proximity to the binding site in order to maximize the redox response to complexation. The sensing process makes use of voltammetric techniques, for example, cyclic voltammetry and the sensors typically target analytes that are not electrochemically active themselves. An overview of the literature is given with a description both of various redox-active groups that have been incorporated into receptors and also the range of targets studied, including cationic, anionic, and neutral species. Recent developments are highlighted that include the development of chiral sensors and receptors that are immobilized at various surfaces, for example, as polymeric species or as self-assembled monolayers.
