| 摘 要： | 在过去的十年内,过渡金属联吡啶配合物的光物理和光化学过程得到了迅速发展,激发态的形成及其决定因素在几类经典的配合物中得以很好的研究,尤其是对d~3组态Cr(bpy)_3~(3+)和d~6电子组态Ru(bpy)_3~(2+)的研究尤为突出.二茂铁及其衍生物一直是有机金属化学研究的重要对象.其对Cr(bpy)_3~(3+),Ru(bpy)_3~(2+)等发光剂猝灭作用对分子器件的基础研究具有重要意义.为此,本文合成了一系列含茂铁基多核配合物,并研究了其对Cr(bpy)_3~(3+)发光过程的猝灭作用.

| Abstract: | Ferrocene-containing ploynuclear metal complexes M(Fe-C(CH_3)=N N=CSSR)_2 (M=Ni~(2+), Cu~(2+), Zn~(2+), Pd~(2+), Co~(2+), Cd~(2+), R=CH_3, CH_2φ) have been synthesized and characterized by cyclic voltummetry. It has been found that this kind of complexes can quench the luminescence of Cr(bpy)_3]~(3+) efficiencily. The Stern-Volmer plot is linear and yield the bimolecular quenching rate constants in order of 10~8～10~9 dm~3·mol~(-1)·s~(-1). The quenching process is carrid out through electron transfer and energy transfer mechanism. |
