Sterically protected tri‐ and hexanuclear platinum clusters were used as building blocks for the high‐yield synthesis of a first‐generation dendrimer (see picture; t Bu 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.
