Self-assembly of an all-thiol-stabilized {Ag28S23} high-nuclearity luminescent nanocluster with a “crab-like” shape†
Abstract
We report a rare all-thiol-stabilized [Ag28(StBu)23]5+ ({Ag28S23} for short) nanocluster with a “crab-like” shape in compound [Ag28(StBu)23](CF3COO)5·8CH3OH (1), which has been synthesized by the self-assembly of AgStBu with CF3COOH, Et3N and KBr/KI in methanol. The diffuse reflection spectrum and luminescence spectra of 1 were investigated.
