Abstract
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
