A new series of dendrimers was prepared by covalently attaching a Newkome dendron, a Fréchet 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 Fréchet dendron. All dendrimers show reversible or quasireversible voltammetric behavior at scan rates in the range 0.10-2.0 V s-1.
通过将纽科姆树枝状分子、弗雷谢树枝状分子和具有氧化还原活性的氨基二茂铁基团共价连接到中心三嗪核上,制备了一系列新的树枝状大分子。与弗雷谢树枝状分子的生长相比,纽科姆树枝状分子的生长对二茂铁残基单电子氧化的半波电位有更显著的影响。所有树枝状大分子在0.10 - 2.0 V s-1范围内的扫描速率下均表现出可逆或准可逆的伏安行为。
