摘要：

The oxidative quenching by a diazonium salt of the excited state of a pyrrole-substituted Ru(bpy)(3)(2+) complex in acetonitrile leads to its polymerization, forming a soluble metallopolymer. The same phenomena is observed with dioxygen as the quencher. The data are consistent with the initial oxidation of the pyrrole moieties by Ru-III species formed upon electron-transfer quenching of [Ru(bpy)(3)](2+*) by O-2. This process appears competitive with pyrrole oxygenation by singlet oxygen formed by energy transfer, due to the subsequent fast polymerization reaction.
