The revelation of numerous thiolate-protected gold nanocluster (TP-AuNCs) structures, achieved through a blend of theoretical predictions and experimental detection/validation, presents a vast amount of data for understanding the structural evolution of these nanoclusters. Typically, these clusters featured an internal gold core surrounded by external “staple” motifs SR[Au(SR)]_x (x = 0, 1, 2, 3, ...) at various charge states. In this Account, we outline our Grand Unified Model (GUM) that elucidates the growth mechanism of the internal gold core, the bonding nature of outer “staple” motifs, and a ring model illuminating the intricate interfacial interactions between the motifs and the internal gold core, as well as a simple rule governing charge states.

揭示硫醇盐保护的金纳米团簇的复杂结构特征：从内部核心到外部“Staple”基序和总体电荷状态

通过理论预测和实验检测/验证相结合，揭示了众多硫醇盐保护的金纳米团簇（TP-AuNC）结构，为理解这些纳米团簇的结构演化提供了大量数据。通常，这些簇的特点是内部金核心被不同电荷状态的外部“主食”图案 SR[Au(SR)] _x ( x = 0, 1, 2, 3, ...) 包围。在这篇文章中，我们概述了我们的大统一模型（GUM），它阐明了内部金核的生长机制、外部“主食”图案的粘合性质，以及阐明图案和内部金之间复杂的界面相互作用的环形模型核心，以及管理电荷态的简单规则。
