Incorporation of dynamic covalent bonds into photomobile liquid-crystalline elastomers with a polysiloxane backbone enables the alignment of mesogens and macroscopic shapes to be controlled through the rearrangement of the network topology, even after the formation of chemically crosslinked networks. The reshaped samples show various sophisticated 3D motions upon irradiation with UV and visible light, depending on their initial shapes.
在聚硅氧烷主链的光致动液晶弹性体中引入动态共价键，使得介晶的排列和宏观形状能够通过网络拓扑结构的重排来控制，即使在形成化学交联网络之后也是如此。根据初始形状的不同，重新成型的样品在紫外光和可见光照射下会表现出各种复杂的 3D 运动。
