| 摘 要： | 合成了Co2+、Ni2+、Cu2+、Cd2+、Zn2+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)32+发光。Stern-Volmer作图呈线性关系并得猝灭速率常数kq为109L·mol-1·s-1数量级,且lgka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。

| Abstract: | Polynuclear complexes containing N and S atoms [M (Fc-C(CH3)= NN = CSSR)2,R=-CH3, -CH2C6H5, M = Co2+, Ni2+, Cu2+, Zn2+, Cd2+] were synthesized. It was found that the coordination compounds could quench *Ru(bpy)32+ with high efficiency. The Stern-Volmer plot is linear and yields the bi-molecular quenching rate constants for these compounds. The quenching luminescence of the " Ru(bpy)32+ proceeded through the electron transfer mechanism. |
