The precise manipulation of nanocluster structures remains highly desirable for disclosing the structure–property correlations at the atomic level. However, the control over a nanocluster (metal kernel + surface ligand) with a maintained template has long been a challenging pursuit, and little has been achieved for manipulation at the atomic level. Here, on the basis of the M₂₉(SR)₁₈(PR′₃)₄ cluster system, the control over the vertex phosphine ligands is accomplished. Therefore, a combination of the manipulation of vertex phosphines in this work and of internal metals and surface thiols reported previously realizes control over the M₂₉(SR)₁₈(PR′₃)₄ cluster template. The principles for regulating the photoluminescence (PL) of M₂₉ clusters via dictation of their metal compositions, surface thiols, and vertex phosphines are exploited to rationally design the most emissive nanocluster among the M₂₉ cluster family. Overall, this work fills the missing part necessary for the manipulation of M₂₉(SR)₁₈(PR′₃)₄ nanoclusters, providing an ideal nanomodel that enables us to grasp the structure–property correlations at the atomic level.

控制Pt1Ag28（S-Adm）18（PR3）4纳米簇的膦配体。

仍然需要对纳米团簇结构进行精确的操纵，以在原子水平上揭示结构与性质之间的相互关系。然而，长期以来，对具有维持模板的纳米簇（金属核+表面配体）的控制一直是一项具有挑战性的工作，并且在原子水平上的操作还很少。在此，M的基础上₂₉（SR）₁₈（PR' ₃）₄集群系统中，在所述顶点的膦配体的控制被完成。因此，在这种工作和内部的金属和表面硫醇的顶点膦的操纵的组合报道先前实现控制所述M ₂₉（SR）₁₈（PR' ₃）_4个集群模板。通过控制M ₂₉簇的金属组成，表面硫醇和顶点膦来调节M ₂₉簇的光致发光（PL）原理，可以合理设计M ₂₉簇家族中最发光的纳米簇。总体而言，这一工作填充必要M的操纵缺失部分₂₉（SR）₁₈（PR' ₃）_4个纳米簇，提供了理想的nanomodel，使我们在原子水平上把握结构-性质关系。
