我们介绍并讨论了最近发展起来的静电自组装的概念，在溶液中形成纳米级组件。与许多依赖于两亲性的自组装方法相反，这里的驱动力是静电加上次级相互作用，例如芳族分子部分的堆叠：聚电解质树枝状聚合物可以与多电荷芳族染料分子连接作为结构抗衡离子，产生100 nm尺度的聚集体，具有窄的尺寸分布和不同的形状。我们讨论竞争的相互作用力和这种方法的潜力，导致多功能和功能的超分子结构。
We introduce and discuss the recently developed concept of electrostatic self-assembly for the formation of nanoscale assemblies in solution. As opposed to many approaches to self-assembly relying on amphiphilicity, the driving force here is electrostatics plus secondary interaction such as stacking of aromatic molecule parts: Polyelectrolyte dendrimers can be linked with multiply charged aromatic dye molecules as structural counterions" yielding 100 nm scale aggregates of narrow size distribution and different shapes. We discuss competing interaction forces and the potential of this approach to lead to versatile and functional supramolecular structures.
