中文摘要：

合成了一种新的以吡啶和酚为配体的混合价态双核金属钌的配合物Ru2BMPB，并对其光谱电化学性能进行了研究．该配合物具有可逆的单电子氧化还原过程（E1／2=0．19V，-0．50V），很好的稳定性（平衡常数K=1．46×10^12）．可见与近红外吸收光谱显示，该配合物在410、665和1580nm处均出现较强的吸收．在可控制的电位下，中心离子Ru的电子转移引起Ru2BMPB的可见与近红外吸收光谱的变化，具有可控制的开关性能．

英文摘要：

A mixed-valence dinuclear ruthenium complex Ru2BMPB was synthesized and its spectroelectrochemistry properties were investigated. The Ru2^ⅡⅢ complex undergoes reversible single-electron reduction （E1/2=- 0.50 V） and oxidation （E1/2 =-0. 19 V） resulting in the Ru2^ⅡⅢ and Ru2^ⅡⅢ complexes, respectively. A comproportionation constant of K =1.46 × 10^12 indicates considerable stability of the mixed-valence state. Three intense, distinguishable, intervalence bands are observed in the visible and near IR spectrum of Ru2 BMPB at 410, 665 and 1 580 nm, and absorption or transmission can be controlled by potential because of the electronic transferring of ruthenium, which exhibits the switch performance.
