理解保护基序和金核之间的界面相互作用对硫醇盐保护的金纳米团簇的稳定性的影响仍然是一个具有挑战性的任务。基于对95个实验结晶和理论预测的硫醇盐保护的金纳米团簇的分析，我们提出了一个环模型，以更深入地了解这类纳米团簇的界面相互作用。在环模型中，所有的金纳米团簇都可以被看作是几个[Au-m（SR）（n）]（m = 4-8，10，12和0
Understanding the effect of interfacial interactions between the protection motifs and gold cores on the stabilities of thiolate-protected gold nanoclusters is still a challenging task. Based on analyses of 95 experimentally crystallized and theoretically predicted thiolate-protected gold nanoclusters, we present a ring model to offer a deeper insight into the interfacial interactions for this class of nanoclusters. In the ring model, all the gold nanoclusters can be generically viewed as a fusion or interlocking of several [Au-m(SR)(n)] (m = 4-8, 10, and 12 and 0
