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.
通过使用基于二芳基联苯并呋喃酮的机械力发色团以及设计嵌段聚合物结构，证明了嵌段聚氨酯弹性体中动态共价键的反复机械断裂和重组。反复的机械化学反应会伴随着明显的变色和同时褪色现象。
