The importance of organic ligands in protecting inorganic nanoparticles and thus imparting the needed stabilization as colloidal dispersions was realised many years ago. Currently, the rational preparation of such nanoparticles with designed organic molecules/ligands resulting in the formation of functional nanoparticles (FNPs) that are tuned for a specific application is an area of immense research interest. The preparation of such FNPs for a desired application requires a clear understanding of the interactions at the nanoparticle (NP)-ligand and ligand-solvent interfaces, and demands a deep appreciation of the surface science and coordination chemistry. In this tutorial review, we briefly explore the evolution of surface-ligand chemistry and inform the readers that, apart from protecting the surface, ligands can modulate the physico-chemical properties of the underlying inorganic NPs as well. This review further presents the design principles for the rational preparation of such FNPs, where one or more ligand shells can be added to the nanoparticle surface, thereby improving the adaptability and amenability of the NP exterior towards the environment in which they are present, as required for a specific application.
多年前就已经意识到，有机配体在保护无机纳米粒子方面的重要性，从而赋予胶体分散体所需的稳定性。目前，用设计的有机分子/配体合理制备具有所需功能的纳米粒子（FNPs），使其针对特定应用进行调整，是一个极具研究兴趣的领域。为特定应用制备此类 FNPs 需要清楚地了解纳米粒子（NP）-配体和配体-溶剂界面的相互作用，并需要深入了解表面科学和配位化学。在本教程综述中，我们简要探讨了表面配体化学的发展，并告知读者，除了保护表面外，配体还可以调节基础无机 NPs 的物理化学性质。本综述进一步介绍了合理制备此类 FNPs 的设计原则，其中可以在纳米粒子表面添加一个或多个配体壳，从而提高 NP 外部对其所处环境的适应性和可处理性，以满足特定应用的要求。
