合成了Co~(2+)、Ni~(2+)、Cu~(2+)、Cd~(2+)、Zn~(2+)等金属的Schiff碱型二茂铁基多核配合物,并对其进行元素分析和光谱表征,发现该类配合物能有效地猝灭Ru(bpy)~(2+)_3发光。Stern-Volmer作图呈线性关系并得猝灭速率常数k_q为10~9L·mol~(-1)·s~(-1)数量级,且lgk_a与配合物的氧化还原电位有较好的线性关系;猝灭过程按电子转移机理进行。
Schiff base ferrocene-based polynuclear complexes were synthesized, including Co ~ (2 +), Ni 2+, Cu 2+, Cd 2+ and Zn 2+. The elemental analysis and spectral characterization showed that these complexes can quench the luminescence of Ru (bpy) ~ (2 +) _3 effectively. Stern-Volmer plotted a linear relationship and the quenching rate constant k_q was on the order of 10 ~ 9L · mol -1 -1 s -1, and lgk_a had a good linear relationship with the redox potential of the complex ; Quenching process by electron transfer mechanism.
