| description | <p>This thesis describes the integration of the halogen bonding iodotriazole motif into a range of interlocked and transition metal based architectures for anion recognition and sensing.</p> <p><b>Chapter One</b> introduces the field of anion supramolecular chemistry, describing the non-covalent interactions exploited by host structures. In particular, this chapter reviews hydrogen bonding and halogen bonding acyclic, macrocyclic and mechanically interlocked molecules for anion recognition.</p> <p><b>Chapter Two</b> describes the synthesis of acyclic and interlocked tetra-iodotriazole based receptors. In particular, the preparation of a family of [2]catenanes and [2]rotaxanes via a chloride anion template approach is discussed, followed by an investigation of their anion binding properties determined through 1H NMR titration experiments.</p> <p><b>Chapter Three</b> presents a new methylene-spaced bis-iodotriazole motif and investigates its ability to complex a range of transition metals for anion recognition and sensing. With the aim of forming a [2]rotaxane via an active metal template method, a range of macrocycles containing the motif are prepared. Towards the construction of a fullerene containing rotaxane, bimetallic C60 fullerene containing halogen bonding and hydrogen bonding anion receptors are prepared and their sensing capabilities investigated via luminescence spectroscopy.</p> <p><b>Chapter Four</b> incorporates a novel benzimidazole-iodotriazole motif into a naphthalimide based axle containing dynamic [2]rotaxane. The requirement for both benzimidazole axle protonation and the presence of a chloride coordinating anion is demonstrated to be crucial for facilitating macrocycle shuttling translocation along the axle component of the [2]rotaxane. The ability of the motif to coordinate photoactive transition metals is also reported.</p> <p><b>Chapter Five</b> presents a summary of the major conclusions from the research described throughout the thesis.</p> <p><b>Chapter Six</b> details the synthetic protocols and characterisation data for each novel compound discussed in the previous chapters. Spectroscopic titration experiment protocols are also outlined.</p> |
