Polymers that release functional smallmolecules in response to mechanical force are promising materials for a variety of applications including drug delivery, catalysis, and sensing. While many different mechanophores have been developed that enable the triggeredrelease of a variety of smallmoleculepayloads, most mechanophores are limited to one specific payloadmolecule. Here, we leverage the
