施主-受主共混体系中的热电荷转移态和电荷产生

Hot Charge Transfer States and Charge Generation in Donor Acceptor Blends

James Kirkpatrick

摘要:

在有机共混物中,激子分裂激发的振动正常模式与耦合到电荷跳跃的振动正常模式相同。因此,如果振动弛豫比电荷转移慢,则用于激子分裂的过量驱动力可以有助于电荷转移。一个模型的开发,考虑到这一点,因此解释了实验观察到的激子分裂和电荷产量的驱动力的关系,可以实现高电荷产量与所观察到的快速重组率。

英文摘要:

In an organic blend the vibrational normal mode excited by exciton splitting is the same as the one coupled to charge hopping. Excess driving force for exciton splitting can therefore aid charge transfer, if vibrational relaxation is slow compared to charge transfer. A model is developed that takes this into account and hence explains the experimentally observed relation of driving force for exciton splitting and charge yield and that high charge yields can be achieved with the observed fast rates of recombination.
