摘　　要：文章采用荧光光谱法研究在六噻吩(6T)/富勒烯(C60,C70和C84)混合液中由电子转移所引起的荧光猝灭现象,并由Stern-Volmer方程分别确定了6T/C60、6T/C70和6T/C84混合液中的双分子猝灭速率常数。结果表明,双分子猝灭速率常数与富勒烯的电子亲和力相关,对6T/C60、6T/C70和6T/C84混合液自由能变化(ΔGCS)的计算进一步证实了该相关性。Fluorescence quenching resulting by the electron transfer in sexithiophene（6T）/fullerenes （C60, C70 and （C84） mixture solution was studied by fluorescence spectroscopy. And the bimolecular quenching rate constants in 6T/C60, 6T/C40 and 6T/C84 mixture solution were obtained by using Stern-Volmer equation. The experimental results show that the bimolecular quenching rate constant is electron affinity-dependent. Calculation of the change in free energy （AGcs） of 6T/C60, 6T/C70 and 6T/C84mixture solution confirms such dependence.
