Large dendritic assemblies terminated by organometallic groups that possess a rich redox chemistry and stability in two or more oxidation states are highly desired as electron-reservoir systems, sensors, and redox catalysts. Here the synthesis and click (CuAAC) chemistry of ethynyl biferrocene including branching onto dendrons, arene-cored dendrimers, and gold nanoparticles are developed, and the role of the 1,2,3-triazole linkers and redox chemistry of these assemblies are discussed including the properties and stabilities of the redox states.
Convergent dendron approach using a phenol triallyl building block: Synthesis of a phenol dendron containing 27 allyl termini

A successful convergent dendron synthesis is achieved using a phenol triallyl (AB3) building block by a sequence of reactions consisting of hydrosilylation-phenol protection. The key feature is the hydrosilylation using dimethylchloromethylsilane that avoids the side dehydrohalogenation previously found with linear branches containing β-hydrogens. The advantage of the AB3 building block is the multiplication of the dendron branches by three at each generation, which allows the synthesis of the second-generation 27-allyl phenol dendron.

Gold nanoparticles have been functionalized with thiol dendrons containing three redox active amidoferrocenyl or silylferrocenyl units; using cyclic voltammetry, these dendronized gold nanoparticles recognize H2PO4-.
