“Development of Polymers with Dramatic and Multifaceted Response to Mechanical Force”
Abstract:
Sensing, transducing, and responding to mechanical force are vital in biomacromolecular systems and for many technologies. In the pursuit of synthetic polymers that can respond to force and dramatically change a whole array of intrinsic material properties at once, we developed an unprecedented type of polymers that rapidly unzip upon being stretched to transform from non-conjugated structures to continuously conjugated structures. We developed several generations of ladder-type mechanophore monomers with increasing synthetic scalability, functional group diversity, thermal stability, and control in their efficient ring-opening metathesis polymerization, opening many new avenues for developing stress-responsive polymers. Mechanistic study also revealed interesting reactivity and dynamic effect in their mechanochemistry, suggesting exciting pathways for effective mechanical transduction and amplification.
