Isolation and structural characterization of magic silver clusters protected by 4-(tert-butyl)benzyl mercaptan

摘要

Small silver clusters (average diameter of 1.2 nm) protected by 4-(tert-butyl)benzyl mercaptan (BBSH) were converted to stable, monodisperse clusters (2.1 nm) by a ripening process with excess amount of BBSH. Multiple characterizations of the isolated magic clusters revealed an approximate chemical composition of Ag∼280(SBB)∼120.
