The ability to control changes in physical and chemical properties has allowed stimuli responsive molecules to be used in a variety of applications. Incorporating metals into stimuli responsive molecules introduces properties unique to metal complexes that allow for additional modes of control. Specifically, metals offer increased bonding geometries, lower dissociation energies, reversible chelation, and well-characterized catalytic properties that expand the chemical toolbox for the design of stimuli responsive molecules. Molecules can be designed to respond to a range of stimuli, including force and light. Towards utilizing force as a useful stimulus, this work describes efforts towards characterizing the behavior of force-responsive metallopolymers by SMFS. Additionally, work towards characterizing photo-physical and metal binding properties of light-responsive aroylhydrazone is explored. This work demonstrates the utility of incorporating metals into stimuli responsive molecules, and provides a framework for the design of future force- and light- responsive metal complexes.
