在这里，我们描述了一种以形成Kagome晶格为目标的三嵌段Janus胶体增强自组装的方法。通过计算机模拟，我们证明了这种难以捉摸的结构的形成可以通过沿着连接其疏水半球的轴线自推进或激活胶体来显著改善。亚稳聚集体失稳并转化为Kagome晶格的过程是相当普遍的，我们认为这种积极的方法为改善大量胶体结构的自组装提供了一条系统的途径。
Here, we describe a method for the enhanced self-assembly of triblock Janus colloids targeted to form a kagome lattice. Using computer simulations, we demonstrate that the formation of this elusive structure can be significantly improved by self-propelling or activating the colloids along the axis connecting their hydrophobic hemispheres. The process by which metastable aggregates are destabilized and transformed into the favored kagome lattice is quite general, and we argue this active approach provides a systematic pathway to improving the self-assembly of a large number of colloidal structures.
