To evaluate the 'slide-ring' effect in a rotaxane cross-linked network, we incorporated mechanochromophores into static and rotaxane cross-linking points and compared the mechanochromisms exhibited by the obtained polymers. This novel strategy reveals a molecular-level phenomenon with visible color changes as well as enabling quantitative electron paramagnetic resonance measurements.
为了评估轮烷交联网络中的“滑环”效应，我们将机械变色团引入静态和轮烷交联点，并比较了所得聚合物表现出的机械变色现象。这种新策略揭示了一种具有可见颜色变化的分子水平现象，同时还能进行定量电子顺磁共振测量。
