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 Nand Satoms [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.
