Ligand exchange reactions are used to achieve nanoparticles coated with a mixture of ligand molecules. Currently, nothing is known on the evolution of the morphology of the ligand shell during the reaction. Here, we use a recently developed method (based on MALDI‐TOF) to follow the evolution of the ligand shell composition and morphology during the reaction. We observe the expected evolution in composition and we find that the ligand shell starts as a random mixture and gradually evolves towards a patchy morphology. When the composition has reached a plateau (i.e. when the reaction is generally assumed to be finished), the ligand shell morphology keeps evolving for days, slowly approaching its equilibrium configuration.

金纳米粒子上的配体交换反应过程中配体壳形貌的演变。

配体交换反应用于获得包覆有配体分子混合物的纳米颗粒。目前，关于反应期间配体壳的形态演变尚无知。在这里，我们使用一种最新开发的方法（基于MALDI-TOF）来跟踪反应过程中配体壳组成和形态的演变。我们观察到了预期的组成演变，并且发现配体壳以随机混合物的形式开始，并逐渐演变成片状形态。当组合物达到平稳状态时（即通常假定反应已完成），配体壳的形态会持续发展数天，逐渐接近其平衡构型。
