Abstract

In response to the application of low electrochemical potentials, ruthenium-tris(bipyridine) complexes decorated with multiple electron-rich and redox-active amine substituents show reversible absorption and emission spectral changes in the deep-red to NIR region. The number of amine substituents strongly affects the electrochemical and spectroscopic properties and the spin density distributions of the complex in the one-electron-oxidized state.

摘要

在低电化学电位的作用下，带有多个富电子且具有氧化还原活性的胺取代基的钌-三联吡啶配合物在深红色至近红外区域显示出可逆的吸收和发射光谱变化。胺取代基的数量强烈影响配合物在单电子氧化态下的电化学和光谱性质以及自旋密度分布。
