Abstract

The types and quantities of surface ligands used in the synthesis of nanomaterials play a dominant role in determining their physical and chemical properties, and this situation likewise occurs in metal-chalcogenide supertetrahedral clusters (MCSCs). The MCSCs are mainly categorized into ligand-fully-protected MCSCs and ligand-free ones according to the surface ligand situation. However, ligand-partially-protected MCSCs are rarely reported. In this study, a facile synthetic strategy was proposed to create ligand-partially-protected MCSCs through the pyrolysis of the S–S or Se–Se bond of disulfide organic ligands in a solvothermal procedure, and a series of Pn-type MCSCs with their surface partially protected by thiophenol ligands (ISC-24-MnSnS: 10(3,5-DMPH+)·[Mn4Sn4S17]10?·4H2O; ISC-25-MnSnS-SPh: 7(3,5-DMPH+)·Mn4Sn4S14(SPh)37?·H2O; ISC-26-MnSnSeCl-SePh: 5.2(3,5-DMPH+)·Mn4Sn4Se12.2Cl0.8(SePh)45.2?·0.8(3,5-DMP)·4H2O; ISC-26-MnSnSeS-SPh: 6(3,5-DMPH+)·Mn4Sn4Se12S(SPh)46?·(3,5-DMP)·4H2O) were obtained. This work could lay a foundation for the synthesis of ligand-partially-protected MCSCs and other partially-protected nanomaterials through the cleavage of disulfide bonds in organic ligands.
