Abstract

Bridging between silver clusters and polyoxoanion clusters, the first 1D assembly, [Ag₃₄(S^tBu)₂₆(W₆O₂₁)(CF₃COO)](CF₃COO)·Et₃N·20CH₃OH (1), based on POM-templated silver-thiolate nanoclusters featuring a [Ag₃₄(S^tBu)₂₆(CF₃COO)]⁷⁺ shell and a [W₆O₂₁]⁶⁻ core is reported. This novel core–shell nanocluster possesses nanoscopic morphology, displays intense deep-blue emission in solution under ambient conditions and also shows special electrochemical properties.
