摘要：

The triplet lifetimes of the ethynyl‐bridged binuclear RuII complexes 1 (m = 0, 1; n = 1, 2) are significantly longer than that of the parent mononuclear complex, despite much lower triplet energies. This effect, which arises from electron delocalization over an extended π* orbital, decreases upon removal of the second RuII cation or if phenyl rings are incorporated into the π‐electron system.
