摘要Using a chloride-assisted supramolecular building-block approach, we have employed the molecular Cl@Ag-m(Cu = CPh)(n) entity in the construction of a gigantic cluster namely [Ag216S56Cl7( Cu CPh)(98)(H2O)(12)][Ag-3(imidazole)(H2O)(4)](SbF6)(2) (1), which contains the largest discrete organometallic cluster investigated by X-ray crystallography. Based on an icosahedral Cl@Ag-12 kernel, this spheroidal cluster features an unprecedented five-shell structure Cl@Ag-12@S-12@ Ag-32@S44Cl6@Ag-172 with idealized Th symmetry. The MALDI-MS, 1D, 2D H-1 NMR, electronic absorption, emission spectra and HR-TEM of 1 were measured. Compound 1 shows intense red luminescence in solution at room temperature (QY = 4.7% in CH2Cl2), in addition to its 3.4 nm diameter, which makes it a unique example that fills the gap between small luminescent silver clusters and large luminescent silver nanoparticles.
