Macromolecules with built-in redox gradients are of much interest due to their potential in a variety of optoelectronic and energy-harvesting applications. In this paper, the design and synthesis of nonconjugated dendrons with redox gradients to guide the charge flow from the core to the periphery is described. The dendrons reported here are based on benzyl ether connectivities. The repeat units of the dendrons are based on triarylamines, and the periphery units of the dendrons are based on N,N,N',N'-tetraarylbenzidine units. The presence of a redox gradient after incorporation of these charge-transporting units into the dendrons is supported by cyclic voltammetric studies.
