| Резюме: | <p>This thesis describes the synthesis and anion recognition properties of a series of halogen and hydrogen bonding acyclic and interlocked host receptors and the use of the inclusion supramolecular chemistry of cucurbit[n]uril derivatives in switchable luminescent output.</p> <p><b>Chapter 1</b> introduces the field of anion supramolecular chemistry and the properties of cucurbit[n]uril macrocycles which pertain to the research detailed in subsequent chapters.</p> <p><b>Chapter 2</b> describes the synthesis and anion recognition properties of a new class of chelating, halogen and hydrogen bonding host molecules. The halogen bonding enhanced selectivity for the Br- anion is demonstrated.</p> <p><b>Chapter 3</b> probes the anion recognition characteristics of a series of novel halogen and hydrogen bonding motifs. Evidence for intramolecular hydrogen bond enhanced halogen bonding recognition of halides is presented and the selective recognition of the anion H2PO4- by a [3]rotaxane host is displayed.</p> <p><b>Chapter 4</b> discusses the redox-mediated modulation of the luminescent output of a series of visible and near-infrared emitting lanthanide complexes within cucurbit[8]uril based ternary complexes.</p> <p><b>Chapter 5</b> describes the experimental procedures and characterisation of the compounds presented in Chapters 2-4.</p> <p><b>Chapter 6</b> summarises the conclusions of this thesis.</p> |
