| Summary: | <p>This thesis describes the synthesis of halogen bonding receptors for integration within interlocked anion host systems.</p> <p><em>Chapter 1</em> introduces the field of supramolecular chemistry, with a particular focus on anion recognition and sensing, halogen bonding, and the synthesis of mechanically interlocked structures.</p> <p><em>Chapter 2</em> describes the preparation and anion binding properties of carbazole-based receptor molecules. A systematic anion binding study on a series of halogen- and hydrogen-bonding 3,6-bis-triazolium carbazole acyclic receptors is described initially, followed by the development of a halogen bonding rotaxane. The anion and metal complexation properties of acyclic and macrocyclic systems incorporating the 1,8-bis-triazole carbazole motif are also presented.</p> <p><em>Chapter 3</em> details the synthesis and anion complexation investigations of halogen and hydrogen bonding naphthalene-based acyclic and interlocked rotaxane host molecules.</p> <p><em>Chapter 4</em> presents receptors based on the 4,4'-bis-triazole-2,2'-bipyridyl motif. A halogen bonding rhenium(I) bipyridyl complex is exploited in the development of a rotaxane host system which optically senses anions via luminescence purely through halogen bonding interactions. The anion recognition and sensing properties of diquat-based receptors are also investigated, and shown to exhibit optical and electrochemical responses to anions.</p> <p><em>Chapter 5</em> summarises the major conclusions from Chapters 2-4.</p> <p><em>Chapter 6</em> describes the experimental procedures used in the work, and includes characterisation data for the synthesised compounds.</p> <p>Supplementary information relating to crystallographic data, and absorption, luminescence and electrochemical studies, is provided in the Appendices.</p>
