A cyclometalated bisruthenium complex bridged by the 2,7-bisdeprotonated form of 1,3,6,8-tetra(pyridin-2-yl)-9-butyl-9H-carbazole displays appreciably enhanced electronic coupling relative to that with the 5,5′-bisdeprotonated form of 3,3′,5,5′-tetra(pyridin-2-yl)-biphenyl as the bridge.
以 2,7 双去质子化形式的 1,3,6,8-四(吡啶-2-基)-9-丁基-9H-咔唑为桥的环甲基化双钌络合物,与以 5,5′ 双去质子化形式的 3,3′,5,5′-四(吡啶-2-基)-联苯为桥的环甲基化双钌络合物相比,显示出明显增强的电子耦合。
