合成了一种新型三脚架配体三[（4 '-甲基-2，2'-联吡啶-4-基）甲基]甲醇（L）。研究了三足桥连配体L连接的新型三核配合物（Ru 2 Re和RuRe 2）的光谱、电化学和光催化性质。此外，在可见光照射下，在CO2的还原中，这些三核配合物的光催化活性得到了2倍的提高，相比于适当的monoclonal模型配合物的混合物。
A novel tripodal ligand, tris[(4'-methyl-2,2'-bipyridyl-4-yl)methyl]-carbinol (L), has been synthesized. The spectroscopic, electrochemical, and photocatalytic properties of the new trinuclear complexes (Ru2Re and RuRe2) linked by the tripodal bridging ligand L are then investigated. In addition, 2-fold-improved photocatalytic activities were obtained in the case of these trinuclear complexes compared to the mixtures of the appropriate monometallic model complexes in the reduction of CO2 under visible irradiation.
