| 摘要: 本文应用时间分辨激光诱导荧光光谱研究了二茂铁衍生物：(C10H6N2)C=N-N=CR-Fc(R=H,CH3,Fc为二茂铁基)与联吡啶钌：(bpy)3Ru2+及一系列钌-铁双核配合物的电子转移和能量传递过程。得到分子间电子转移和能量传递过程的速率常数约为109dm3mol-1s-1,而分子内传递过程的速率常数约为107dm3mol-1s-1,证实了分子内传递过程比分子间传递过程进行得更彻底。并用Marcus理论计算了分子间传递过程的速率常数,探讨了转移机理,讨论了瞬态法和稳态法所得结果的差异。 |

| Abstract: In this paper, the p rocess of electron and energy transfer in a kind of ferrocene deriva-tives (C10H6N2)C=N-N=CR-Fc(R=H,CH3, Fc is ferrocene) with (bpy)3Ru2+ and a series Ru(Ⅱ)-Fe(Ⅱ)double-center complexes are studied using the method of tine resolved LIF spectroscopy. The rate constants of intermolecular process are obtained to be about 109dm3mol-1s-1 and that of intramolecular process are about 107dm3mol-1s-1.The result proved that the intramolecular transfer is deeper than the intermolecular process The difference betty een the resu It of in staneous state method and steady state method is discussed using the theory of Marcus. |
