重复的机械断裂和重组的动态共价键纳入分段聚氨酯弹性体证明通过利用二芳基bibenzofuranone为基础的mechanophore和设计的分段聚合物结构。重复的机械化学反应可以伴随着清晰的着色和同时褪色。
Repeated mechanical scission and recombination of dynamic covalent bonds incorporated in segmented polyurethane elastomers are demonstrated by utilizing a diarylbibenzofuranone-based mechanophore and by the design of the segmented polymer structures. The repeated mechanochemical reactions can accompany clear colouration and simultaneous fading.
