研究了由金和聚合物嵌段结构域组成的两组分和三组分棒状积木的组装性能。这些结构的行为类似于介观的两亲分子，并根据组成周期形成一系列由束、管和片组成的单层超结构。与分子系统不同，最初用于合成它们的模板在组装过程中起着关键作用，它通过预先对它们进行排列，通过在模板溶解时优化正确的碰撞方向来促进它们的组装。基于对混合棒填充参数的估计，可以以可预测的方式组装具有可调整直径的管状结构。
The assembly properties of two- and three-component rod-like building blocks consisting of gold and polymer block domains have been investigated. These structures behave like mesoscopic amphiphiles and form a series of single-layer superstructures consisting of bundles, tubes, and sheets depending upon the compositional periodicity. Unlike molecular systems, the template used to initially synthesize them plays a critical role in the assembly process by prealigning them in a manner that facilitates their assembly by optimizing the correct collisional orientation upon dissolution of the template. Tubular structures with tailorable diameters can be assembled in a predictable manner on the basis of an estimate of the hybrid rod packing parameters.
