Molecular Junctions and Nanostructures

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.
