Fine Controlled Metallodendrimers for Advanced Nano-Catalysts
Dendrimers are highly branched organic macromolecules with successive layers or “generations” of branch units surrounding a central core. We show that tinchlorides complexes to the imines groups of a spherical polyphenylazomethine dendrimer in a stepwise fashion according to an electron gradient, with complexation in a more peripheral generation proceeding only after complexation in generations closer to the core has been completed. By further extending this strategy, it should be possible to control the number and location of metalchlorides incorporated into dendrimers for advanced nano-materials, such as nano-catalysts.
