合成了含二氮芴和联吡啶等配体的一系列新型钌铁双核配合物:[(C~1~0H~6N~2)C=N-N=CR-Fc)Ru(bpy)~2]·(PF~6)~2,[(C~1~0H~6N~2)C=N--C~6H~4-N=CR-Fc)Ru(bpy)~2]·(PF~6)~2,[(C~1~0H~6N~2)C=N-C~6H~4-C~6H~4-N=CR-Fc)Ru(bpy)~2]·(PF~6)~2,并对其进行了光谱表征,通过对该类配合物的循环伏安和发光光谱研究,讨论其激发态的氧化还原性和对[Ru(bpy)~3]^2^+发光过程的猝灭作用.研究表明猝灭过程为扩散控制的双分子交换能量传递

Ru(II)-Fe(II) binuclear complexes, cis-[Ru(bpy)2((C10H6N2)C:NN:CRFc)][(PF6)2], cis-[Ru(bpy)2((C10H6N2)C:NC6H4N:CRFc)][(PF6)2] and cis-[Ru(bpy)2((C10H6N2)C:NC6H4C6H4N:CRFc)][(PF6)2] (Fc = ferrocenyl; (C10H6N2)C:O = 4,5-diazafluoren-9-one) were synthesized and characterized. The redox property of the excited state and their quenching of the luminescence of [Ru(bpy)3]2+ are discussed through the study of the emission spectrum and the cyclic voltammetry. The quenching mechanism of bimol. exchange energy-transfer is also discussed.
