Rotaxanes are Mechanically Interlocked Molecules (MIMs) formed by a dumbbell-shaped axle and a macrocyclic wheel, which cannot be separated without breaking a covalent bond. Incorporation of rotaxanes into Metal-Organic Frameworks (MOFs) produces organized, dense solid-state systems. This thesis describes the synthesis and study of novel  and bis(benzimidazolium) rotaxanes, including shuttling studies and MOF synthesis. Chapter 1 provides an introduction to MIMs and molecular shuttling, in solution and solid-state. The idea of incorporating MIMs into MOFs is addressed. Chapter 2 describes the synthesis of two new rotaxanes as well as preliminary study of a cucurbituril pseudorotaxane. Shuttling studies of the rotaxane in solution were conducted. MOF synthesis incorporating both the  and rotaxanes as linkers and analysis of PXRD patterns to determine the probable structures of the MOFs. Finally, summary and possible future work are described. Chapter 3 describes all of the experimental details including the full synthetic procedure for the preparation of  and rotaxanes and relevant characterisation data.
