A new cyclometalating bridging ligand 1,3,6,8-tetra(2-pyridyl)pyrene was designed and synthesized through 4-fold Suzuki couplings between 1,3,6,8-tetrabromopyrene and 2-pyridylboronate. A bis-cyclometalated bisruthenium complex bridged by this ligand showed the presence of an electronic coupling between individual metal centers, as indicated by electrochemical and spectroscopic studies.
一种新型的环金属桥联配体 1,3,6,8-四(2-吡啶基)芘通过 1,3,6,8-四溴芘与 2-吡啶硼酸酯之间的 4 倍 Suzuki 偶联反应设计并合成。由该配体桥联的双环金属双钌配合物表明在各个金属中心之间存在电子耦合，这可通过电化学和光谱研究来指示。
