Mechanophore activation is usually performed on chain-centred or multi-mechanophore polymers. Here we investigate the activation of a bis-mechanophore system where two identical Diels–Alder adduct mechanophores are joined together with a short linker. Although CoGEF calculations suggest that the presence of a mechanophore affects the mechanochemical coupling of an adjacent mechanophore, we found no difference in the scission rate between various bis-mechanophore systems and their respective mono-mechanophore reference when activated by ultrasound in solution.

机械活化包含两个相邻机制的聚合物

力学活化通常是在以链为中心或多力学的聚合物上进行的。在这里，我们研究了双机制系统的激活，其中两个相同的Diels-Alder加合物机制通过短连接子连接在一起。尽管CoGEF计算表明，机械力的存在会影响相邻机械力的机械化学耦合，但是当溶液中超声激活时，我们发现各种双机械力系统与其各自的单机械力参考之间的分裂速率没有差异。
