Leverage of Molecular and Macromolecular Architectures for Mechanically Responsive Materials
Abstract
The technical objective of the proposed effort is to explore the fundamental aspects for force-activation of functional groups and their coupl ing to the macroscopic matrices. The proposed effort seeks to achieve the stated technical objective through exploring three specific technical aims. First, the proposed research will investigate a range of strained compounds and heterocycles as new mechanophores, which have the potential to change optical, electronic, and mechanical properties in response to mechanical stimuli. Second, the proposed work will characterize the force coupling in complex macromolecular and network architectures to enable molecular level understanding of force transduction in these matrices. Third, the proposed effort will design sensitive absorption and fluorescence based assays to monitor the mechanochemical events in situ. The research will seek to investigate a range of functional groups unexplored for mechanochemistry in order to: mechanically trigger a change of intrinsic material properties, such as conductivity, crystallinity, and mechanical strength; and use mechanophores to dissipate detrimental mechanical energy and remodel materials.
