Mechanophores have become a very useful tool to study mechanical stress at the molecular level, as well as a method for detection of mechanical damage. However, optical signals from such mechanophores are limited by light-scattering or simply by the polymer color. Gas-releasing mechanophores are an interesting alternative, which provide a chemical signal which can easily leave a polymer matrix and be detected, although the precise location for the damage is lost. Here the development of a flex-activated CO-releasing mechanophore is presented, and the mechanophore is included in a PMMA network. Upon testing, this mechanophore releases CO in large amounts, which could be detected even with a commercial household CO-detector.

用于机械损伤检测的柔性激活 CO 机械化学生产
机械载体已成为在分子水平上研究机械应力的非常有用的工具，以及检测机械损伤的方法。然而，来自这种机械载体的光信号受到光散射或仅仅受到聚合物颜色的限制。释放气体的机械载体是一种有趣的替代方案，它提供的化学信号可以很容易地离开聚合物基质并被检测到，尽管损坏的精确位置丢失了。这里介绍了一种柔性激活的释放 CO 的机械载体的开发，该机械载体包含在 PMMA 网络中。经过测试，这种机械载体会释放大量 CO，即使使用商用家用 CO 检测器也可以检测到。
