摘　　要：研究二茂铁衍生物对Ru(bpy)32+的发光猝灭.按照文献[8-9]合成7种二茂铁衍生物,发现它们对Ru(bpy)32+的发光有明显的猝灭作用,通过Stern-Volmer公式分别求出了它们的猝灭速率常数kg和自由能变△G.研究了它们猝灭Ru(bpy)32+发光过程中的电子转移机理.This paper was focused on the suppression of ferrocene derivatives to Ru（bpy）3^2＋.Seven ferrocene derivatives were synthesized according to the literature method,which were found to have an apparent quenching effect on the luminescence from Ru（bpy）3^2＋.Their quenching rate constants（kg） and the free energy change（△G） were also obtained from the Stern-Volmer equation.The electron transition mechanism was also investigated in the processes of luminescence from the suppression for the seven ferrocene derivatives to Ru（bpy）3^2＋.
