Force-Promoted Transformations in Mechanically Linked Molecules

Research output: Chapter in Book/Report/Conference proceedingChapter


The application of external force to mechanical bonds allows for the investigation of how these architectures behave to various levels of force, leading to useful applications in force-responsive systems. This chapter covers different techniques used to study the response of mechanical bonds to a range of forces. Single-molecule force spectroscopy (SMFS) can be used to study responses to force in the pN range, including the disruption and reformation of non-covalent interactions within the component parts of mechanical bonds. Ultrasonication activation has been used to investigate the dissociation mechanism of catenanes and rotaxanes in the nN force regime. Finally, solid-state activation has led to the use of mechanical bonds within force-responsive materials. The studies in this chapter highlight the useful properties of the mechanical bond in the development of force-responsive systems on both the small scale within single molecules and the development of smart materials.
