Atom-hybridization for synthesis of polymetallic clusters.

ABSTRACT: The chemistry of metal clusters on the sub-nanometer scale is not yet well understood because metal clusters, especially multimetallic clusters, are difficult to synthesize with control over size and composition. The template synthesis of multimetallic sub-nanoclusters is achieved using a phenylazomethine dendrimer as a macromolecular template. Its intramolecular potential gradient allows the precise uptake of metal precursor complexes containing up to eight elements on the template. The usefulness of this method is demonstrated by synthesizing multimetallic sub-nanoclusters composed of five elements (Ga₁In₁Au₃Bi₂Sn₆). The size and composition of this cluster can be precisely controlled and the metals involved are alloyed with each oth
