| description | <p>This thesis describes the investigation of halogen bonding and hydrogen bonding anion receptors for the electrochemical sensing of anions in solution and at receptor-modified electrodes.</p>
<p><b>Chapter 1</b> introduces the general concepts of supramolecular host-guest chemistry and electrochemical anion sensing. A range of voltammetric, impedimetric and potentiometric anion sensors and their basic operational principles are discussed.</p>
<p><b>Chapter 2 </b>describes redox-active ferrocene- or osmium (II) bipyridyl-containing anion receptors for the voltammetric detection of anions in aqueous-organic solvent systems. This includes detailed studies and comparisons of voltammetric sensing under diffusive as well as surface-confined conditions.</p>
<p><b>Chapter 3</b> explores the unprecedented use of non-Faradaic capacitance spectroscopy for the sensing of anions in pure water. This is demonstrated at surface-immobilised foldamer receptors enabling the selective sensing of perrhenate, thiocyanate and iodide.</p>
<p><b>Chapter 4</b> expands on the use of the capacitive methodology developed in Chapter 3 for the enantioselective detection of anions at chiral molecular films.</p>
<p><b>Chapter 5</b> investigates the sensing of ion-pairs via non-Faradaic capacitance spectroscopy at surface-confined heteroditopic receptors.</p>
