So wie mechanischer Druck schöne Klänge auf einer Geige erzeugt, kann die mechanische Belastung von Polymeren zu interessanten chemischen Reaktionen führen. In der Zuschrift auf S. 3092 ff. stellen W. Weng et al. ein Spirothiopyran‐Polymer vor, das bei Einwirkung einer mechanischen Kraft hellgrün leuchtet und Quervernetzung eingeht. Zwei charakteristische mechanische Antworten auf eine mechanische...
Incorporation of small reactive moieties, the reactivity of which depends on externally imposed load (so‐called mechanophores) into polymer chains offers access to a broad range of stress‐responsive materials. Here, we report that polymers incorporating spirothiopyran (STP) manifest both green mechanochromism and load‐induced addition reactions in solution and solid. Stretching a macromolecule containing...
