含席夫碱桥联配体的双核金属钌配合物的合成及其性能研究 总被引:2,自引:2,他引:0
合成了3种双核钌配合物[Ru(bpy)2]2{[(PyCHN)-Ph-O-C6H4-]2R}(ClO4)4,bpy=2,2′-联吡啶,PyCHN=N-2-吡啶亚甲基,R=无(1),-C(CH3)2(2),-SO2(3)并进行了有关表征。电化学研究表明:配合物3的ΔE和Kc值最大,说明苯环和硫原子之间存在着较强的(p(π)-d)π相互作用,有助于获得较强的金属-金属相互作用。配合物1,2,3都有混合价,通过Hush方程可以得到Vab的值大概为320~420 cm-1。这些结果表明:Schiff碱作为桥配体对于调配金属-金属相互作用并将其作为分子导线起着特殊的作用。 相似文献
