Sparsely modified surfaces can be used as a general platform for precisely modifying small nanoparticles. However, strictly, rather than statistically, sparse surface modification remains a big challenge. Herein, we report a new and general method for strictly sparse modification of the surface of relatively large nanoparticles. The method is analogous to planting big trees and then removing the big crowns, leaving the stumps on the ground; due to the large exclusive size of the crowns, the stumps are strictly sparsely distributed. As a proof of concept, strictly sparse modification of surfaces was demonstrated by the successful preparation of “monovalent” and “divalent” golden nanoparticles (AuNPs) with different sizes. Starting from the “monovalent” and “divalent” AuNPs, AuNP dimers and chain-like AuNP assemblies were prepared, respectively.

严格稀疏的表面修饰及其在具有精确“价数”的纳米粒子的赋予中的应用

稀疏改性的表面可以用作精确修饰小的纳米粒子的通用平台。但是，严格地而不是统计地，稀疏的表面修饰仍然是一个巨大的挑战。在这里，我们报告了一种新的通用方法，用于对相对较大的纳米粒子的表面进行严格稀疏修饰。该方法类似于种植大树，然后去除大树冠，将树桩留在地面上。由于冠的专有尺寸较大，因此树桩严格稀疏分布。作为概念的证明，通过成功制备具有不同尺寸的“单价”和“二价”金纳米颗粒（AuNP），证明了对表面的严格稀疏修饰。从“单价”和“二价” AuNPs出发，分别制备了AuNP二聚体和链状AuNP组装体。
