A team from the Johnson, Olsen, Kulik, and Craig labs report a class of force-responsive molecules—tetrafunctional cyclobutanes (TCBs)—that enable the synthesis of single-network end-linked gels with substantially decreased or increased toughness, including unusually high toughness for dilute end-linked gels, with no other changes to network composition. TCB mechanophores and the corresponding concepts of stress-selective force-coupled reactivity and strand continuity offer design principles for tuning the toughness of simple yet commonly used single-network gels.
