Redox active, hybrid dendrimers containing Frechet- and Newkome-type blocks

A new series of dendrimers was prepared by covalently attaching a Newkome dendron, a Frechet dendron, and a redox active, aminoferrocene group to a central triazine core. Growth of the Newkome dendron has a more pronounced effect on the half-wave potential for the one-electron oxidation of the ferrocene residue than growth of the Frechet dendron. All dendrimers show reversible or quasireversible voltammetric behavior at scan rates in the range 0.10-2.0 V s(-1).
