Abstract:

This thesis is primarily concerned with the synthesis and characterisation of heterometallic polynuclear coordination structures, but also contains host-guest studies of mononuclear complexes. Chapter One consists of an introduction to self-assembly and supramolecular chemistry. Recent examples of coordination cages are given along with previous work from the Ward group. An introduction to recent efforts in the field of heterometallic supramolecular chemistry is also given. Chapter Two describes the use of a series of mononuclear Ru(II) complexes to act as models for the vertices of coordinati

Abstract:

Supramolecular cage complexes are of great interest, not only for their structural elegance, but also for their applications. Chapter 1 describes a collection of the many types of cage complexes based on three-dimensional polyhedral shapes and the host-guest chemistry that some cages complexes, enabled by their central cavities, are able to exhibit as they encapsulate small molecules. This thesis contains a number of studies, starting with an investigation into the host-guest chemistry of the tetrahedral cage complex [M4(Lbip)6⊃(BF4)](BF4)7 [where M = Co(II) or Cd(II)].

Abstract:

Various technologies depend on interfacial events that are influenced by various molecular interactions at a solid-liquid interface. The functionality of a surface plays an important role in many applications such as catalysis, sensing, and bio-compatibility, which can benefit from distinctive chemical and physical surface properties. To create tailor-made functional surfaces, surface host-guest assemblies based on Langmuir-Blodgett and self-assembly technique have been employed as a model system as they may offer the potential ability to regenerate surface properties via intercalation of vari

In summary, a series of polytopic ligands based on NHC and MIC ligands have been synthesized in this Doctoral Thesis by means of different synthetic routes that gave rise to systems with very sophisticated architectures.

Abstract:

This thesis discusses progress made towards assembling molecular building blocks in the presence of our molecular host of choice, cucurbit[8]uril (CB[8]). Our studies on the self-assembly of synthetic and biological components in water bridge overlapping conceptsand techniques drawn from the fields of synthetic organic chemistry, supramolecular self-assembly, and applied NMR techniques. Chapter 1 introduces the reader to chemical complexity, and how supramolecular chemistshave advanced in their capability of assembling more complex molecular architectures.

Coordination-driven self-assembly has led to the realization of an increasing number of elegant and sophisticated functional structures, the structural complexity of which would be difficult to achieve using conventional covalent chemistry. The synthesis of three-dimensional coordination capsule-like structures is of particular interest due to their multiple potential applications, particularly their use in selective molecular recognition (host-guest chemistry), reactivity modulation (nanoreactors), molecular sensors or biological applications.

Abstract:

Supramolecular host-guest chemistry is a topic of great current interest. However, the further development of host-guest chemistry is still limited by the number of available host-guest recognition motifs. This makes it necessary and valuable to find new host-guest recognition motifs and apply known host-guest recognition motifs in the preparation of novel supramolecular systems. By comparing the crystal structures of the host and its taco complex, we proved that folding is a necessary step during the formation of taco complexes.

Abstract:

The convergence of supramolecular and polymer sciences has led to the construction of analogs of traditional covalently-constructed polymeric structures and architectures by supramolecular methods. Host-guest complexations of polymers are also possible through well-defined synthesis of polymeric building blocks, for novel supramolecular polymers. Monotopic polymeric building blocks were synthesized by controlled radical polymerizations with a crown or paraquat initiator. The combinations of terminal and central functionalities of host and guest polymeric building blocks provided chain-extended
