The synthesis and investigation of the electronic properties of crown ether, [2]-catenane, and [2]-rotaxane architectures
… of donor-acceptor architectures of the pseudorotaxane, rotaxane, and catenane genres. The binding constants of thiophene and phenylene-ethynylene based crown ethers are determined via fluorescence quenching titrations, in an attempt to correlate structure with binding affinities. The insight …

New Liquid Crystalline [2]Rotaxanes
… study structure-property relationships between rotaxane design and mesomorphism. Chapter 1 introduces concepts of supramolecular chemistry and liquid crystals and cooperative effect between [2]rotaxane and liquid crystals towards functional molecular machines. In Chapter 2, a systematic approach …

Syntheses and characterization of copper(I) complexes for study of dynamic supramolecular ring-chain equilibria and application as photoredox catalysts
… molecules (MIMs), such as rotaxanes, catenanes and pseudorotaxanes. The discovery of 1,10-phenanthroline and its use as a ligand for application in the coordination and supramolecular chemistry fields dates back to the late nineteenth century. As ligands, 1,10-phenanthroline …

New Rotaxane Ligands with Donors on Both the Axle and Wheel
… the design, synthesis and characterization of [2]rotaxane, [2]pseudorotaxane and [3]rotaxane ligands and their resulting coordination to metal centers. Chapter 1 introduces the concepts of interpenetrated and interlocked molecules, molecular motion, metal-ligand interactions and metal organic …

Hydroxy and amidinium containing acyclic and interlocked anion receptors
… synthesis of two cationic hydroxy containing [2]rotaxanes and compares their anion binding abilities to a previously reported analogous [2]rotaxane without hydroxy groups. Along with 1H NMR solution anion binding studies, the binding modes of these three [2]rotaxanes to various anions was …

Mechanical Processes of a Single Synthetic Molecular Machine Studied by AFM-based Force Spectroscopy
… submolecular components in a hydrogen-bonded [2]rotaxane -a molecular ring threaded onto a molecular axle- can be harnessed to generate significant directional forces. We used the cantilever of an atomic force microscope to apply a mechanical load to the ring during single-molecule …

Mechanically Interlocked Linkers for Dynamic Metal-Organic Frameworks
… all previous work towards incorporation of rotaxane linkers into metal-organic frameworks. Chapter 2 describes how a paradigm shift in the development of such systems resulted in a robust rotaxane linker that was used to create a novel material, UWDM-1 (University of Windsor Dynamic …

Design, Preparation and Characterization of Novel Pseudorotaxanes, Semirotaxanes, Rotaxanes, Non-Covalent Supramolecular Polymers and Polycatenanes
… of novel host/guest systems, such as pseudorotaxanes, semirotaxanes, rotaxanes and catenanes, with high association constants, enhanced yields and the abilities to respond to external stimuli are of great importance and significance due to their topological novelty and potential application. …
