摘要 研究系列有机染料在水溶液中对Ru(bpy)3Cl2的发光淬灭,发现它们对Ru(bpy)3Cl2的发光有显著的猝灭作用。Ru(bpy)3Cl2发光淬灭符合Stern-Vo lmer方程,通过Stern-Vo lmer公式分别计算出了对应染料的猝灭速率常数Kg。研究分析了不同化合物的结构对淬灭速率常数的影响,筛选出对配合物发光高效猝灭的有机染料。 Fluorescence quenching of Ru(bp-y)3Cl2 by a series of organic dyes has been investigated by using the steady state fluorescence technique in aqueous medium. The quenching of [Ru(bpy)3]2+. was found to obey theStern-Vohner equation and the corre- sponding Stern-Vohner plots were linear indicating dynamic quenching.The research on the analysis of the structure of different compounds on the influence of quenching rate constants Kg.
