Abstract

The tert-butylethynide ligand has been employed to construct an atomically precise all-tert-butylethynide-protected silver superatom nanocluster, Ag₅₁(^tBuC [triple bond, length as m-dash] C)₃₂ (hereafter denoted as Ag₅₁). The identity of Ag₅₁ is confirmed by high resolution ESI-MS and elemental analysis. Single crystal X-ray analysis revealed that the structure of Ag₅₁ features a three-shell arrangement, Ag@Ag₈/Ag₆@Ag₃₆@C₂₄/C₈. Ag₅₁ exhibits a strong solvatochromic effect, and the emissions are strongly dependent on the solvent polarity and are tunable from blue to red by changing the solvent from less polar dichloromethane to highly polar methanol.
