Assembling Metal Clusters with Covalent Linkers: Synthesis and Structure of a Quasi‐Planar Pt₁₈ Dendrimer Containing Five Clusters Connected by σ‐Alkynyl Spacers

Abstract

Sterically protected tri- and hexanuclear platinum clusters were used as building blocks for the high-yield synthesis of a first-generation dendrimer (see picture; tBu groups are omitted for clarity), which is chemically and thermally stable, and in which the cluster units are separated by conjugated 1,3,5-triethynylphenyl groups.
