我们提出了一种在溶液中组织金属纳米粒子的方法,该方法基于疏水作用,不需要氢键或分子识别。当两亲性 V 形分子附着在金簇上时,水溶液中会发生聚集过程,并导致形成明确的圆柱状和囊状纳米颗粒阵列。金属团簇在将疏水核与杂化胶束状聚集体的亲水冠分离的边界处密集堆积。这种设计允许人们以可逆的方式组装和拆卸纳米粒子,并通过改变溶液制备的条件来控制阵列的尺寸和形态。

We describe a synthesis of a dendrimer-like amphiphile containing a flat rigid core and 12 hydrophobic and hydrophilic arms. We employ a modular approach based on stepwise protection chemistry starting from simple building blocks. The key feature of this approach is the absence of a polymerization step, which makes it applicable for linear monofunctionalized precursors of any kind. This strategy also allows for precise control of the number of arms and ensures their alternating arrangement.

method for organizing metallic nanoparticles in solution that is based on the hydrophobic effect and does not require either hydrogenbonding or molecular recognition. When amphiphilic V-shaped molecules are attached to a gold cluster, an aggregation process ensues in aqueoussolution and leads to the formation of well-defined cylindrical and vesicular nanoarrays of particles. The metallic clusters
