exploiting the bending behavior of surface-assembled diarylethene crystals is reported. A photoactuated smart surface based on this system can transport polystyrene beads to a desired area depending on the direction of the incident light. Two main challenges were addressed to accomplish directional motion along a surface: first, the preparation of crystals whose bending behavior depends on the direction
报道了利用表面组装的二芳基乙烯晶体的弯曲行为的物体运输系统的设计。基于此系统的光致智能表面可以根据入射光的方向将聚苯乙烯珠粒传输到所需区域。解决沿表面定向运动的两个主要挑战:第一,制备晶体的弯曲行为取决于入射光的方向。第二,制备在其上排列了这些光致变色晶体板的膜。通过使用粗糙度控制的点状微结构化基底,可以实现核生成和核生长工程。该系统演示了如何实现机械功能,如沿表面的远程控制运动所示。
